'94 Buick Regal stalls while driving in town

Showing 4 out of 4 Posts
Question From Please help! on '94 Buick Regal stalls while driving in town

Car started missing bad during summer...thought it was cat conv. Engine light on and off, code was cam shaft sensor. Then in the fall of 2012, it stalled one morning after running errands. Stalled when taking off at stop light. Would not start back up for at least 20 minutes so we had it towed home. Started up no problem by the time we got it home. Husband drove the heck out of it for about 15 minutes and no stalling. I drove it the next day and stalled on me again and didn't want to start up. All gauges lit up before it died that time. Took it to a shop and engine light wouldn't come back on for a few days so shop couldn't read codes. Shop replaced fuel pump after having my car for a month and the fuel pressure at 38 being the only reason mechanic could come up with for it stalling. Also had husband replace cam sensor. A whole lot of money later, engine light still on and stalled on me when I was coming home from shop. Friend said it may be a distributor cap...?? I think it is electrical....Please help! I think it is 3.4 L and has 130,000 miles on it. Thank you. Molly

Response From Hammer Time

Took it to a shop and engine light wouldn't come back on for a few days so shop couldn't read codes.

That's just nonsense. All codes are stored in the computer to be retrieved at any time until they are erased.

You say the light is on now..... what is the code number?

Response From Please help! Top Rated Answer

So I haven't driven my car for about two weeks and light comes on after driving for about 5 minutes. I don't have a code reader but back in august the reader said cam shaft sensor so we replaced that a few months ago. I know it sounds like nonsense or maybe a lazy mechanic....? However, he told me my car is just old enough that it wasn't until '95 or so that the computers in these cars were more universal. "My car is not compatible and harder to diagnose" he says. So it sits until I have an idea of which way to go next. I'm putting a call into mechanic and I will get back as far as codes. Thank you

Also, would the cat. converter have anything to do with the stalling?

Response From Tom Greenleaf

Some Buicks were OBD II in 95 I think not in 94 TMK. Codes are just counting blinks of CEL with key on which will repeat.

Probably near impossible to find now but a handy thing was just $20 for these and told you all the codes and what they meant in a small book.

AYOR if you read codes with a paper clip method like this - AYOR as said............


The tool just jumps those too but gives you the book on what to expect looks like this.........


If your CEL has been on it has some info for you. Again - AYOR at jumping things as doing that wrong who knows what damage you can cause?

Ask you mechanic if he even still deals with OBDI systems or has the data or gadget to do it,

1978 Buick Electra stalls after Cold Start & then does not start agin

Showing 2 out of 2 Posts
Question From LARRYS on 1978 Buick Electra stalls after Cold Start & then does not start agin

I have a 1978 Buick Electra 225, 350 X cubic inch engine, 4 barrel carbuerator. I have had this car since 1986 and have babied it and usually have it in A-1 condition. Just recently, upon cold starts after not driving the car for a day or so, the car does start up & runs but suddenly the engine dies/stops/stalls. Upon trying to re-start the car,the starter cranks but it does not re-start-up. The carbuerator choke plate is closed at initial cold start-up & then does start to open up after first starting the car. If I leave the car until the next day, it usually does re-start but again eventually it stalls with subsequent inability to immediately re-start the car. I have applied starting fluid spray after the engine stalls/stops but it does not re-start the car.

I have tried the following recently: have been adding gas line anti-freeze, have changed the fuel filter, and a few months ago changed the spark plugs, ignition cables, distributor cap/rotor.

Your ideas on how to correct this problem would be greatly appreciated. For years, I have had no issues with cold starts & if the card did stall, it always immediately re-started up.

Thank you, Larry S.

Response From Discretesignals Top Rated Answer

When it won't start, does it have spark? Nice big fat blueish spark?

If you hold the gas pedal to the floor while cranking, will it fire up when it doesn't want to start?

How is the engine cranking speed? Has the battery been tested? Was it fully charged when your problem was occurring?

Exploding Muffler

Question From GlennC1 on Exploding Muffler

Okay, I have a '79 Buick regal (231CID/3.8L with carburetor & HEI). Last night I was driving home down the FWY about 11:00 PM when the car suddenly loses power. Then it would pick up again,lose power again. So I decided I would try to nurse it home in the slow lane, about 50 MPH. All of a sudden I hear a loud BOOM and I see a large fireball in the rear view mirror. Scared the s@#% out of me. The exhaust was much louder after that. I got off at the first exit. It was dark but other than the exhaust noise the car seemed alright. Got it home,jacked it up and found the muffler had exploded. It was buckled in the middle and one of the end caps was blown almost completely off. I can replace the muffler easy enough,the question is:What happened? This car has been in the family since it was new and I maintain it well. It's never done this before. Since it didn't just pop the seams, and it actually exploded with a fireball it must have had a combustible mixture accumulate. This would lead to the carburetor.....I guess. Anybody ever heard of this before? Any input would be appreciated. It was kind of funny though: There was no traffic on the FWY except for me and one other car, also in the slow lane, behind me. When the muffler exploded He/She crossed four lanes of empty FWY to the far left and took off at a high rate of speed. Who knows what he thought was happening ha,ha,ha,ha,ha,ha,. Thanks.

Response From Discretesignals

Glad to read you got it figured out and repaired Thanks for the follow up. Closed as solved. Can be reopened upon request by the OP.

Response From GlennC1 Top Rated Answer

Got it fixed. New muffler,good quality one. The wire going to distributor cap for the coil chaffed on something,probably the air cleaner. I could actually see where it had been arcing. That was a great call with the ignition system,thanks guys.

Problem on this HEI distributor could be made worse if the carbon spring loaded thing from coil to rotor is broken or missing. Just lift up cap and look at that would make it want to seek alternate ways to spark if bad. Can't recall right now if sold separately or only with coil?

That center thing underside of cap should be a pencil eraser size carbon pile pushed by a spring. This showed only $20 for whole thing - new coil + would do rotor while there,

Response From Discretesignals

Something happened with the ignition system. Either it lost power from the ignition switch intermittently or there is another problem inside the distributor such as the ignition control module, pickup or wiring. What happened was that the ignition timing was altered from one or more of the possible scenarios from above causing the backfire.

Response From Tom Greenleaf

Glad you can't see me laughing a little and it's not funny. I've seen that a couple times with even fairly new mufflers blow out by the seam - always cheap ones.


That's not why though. Might be two things going on. Ignition could make the spark and a choke that doesn't shut off all the way over fuel and get hot but raw gas in the muffler. Choke would also cause loss of power but a smoother loss unless you about floored it forces choke open a bit more and BOOM from any spark issue or flake of junk moving along.


It's a '79 so plenty should already be done or checked if lots is mostly original by chance and could be. Close to some changes, could this cat converter possibly still be original? Some just a couple model years earlier were full of pellets with the thinking you could dump those for new ones which nobody did but a screen to keep them inside at the back if let go pellets could go out exhaust red hot especially if over loaded with gas.


Whatever you find to fix the reason do buy a muffler that's fully guaranteed even for this as it did seem to happen only to the real cheap ones,

Question From 3izarre on I'm literally driving Dr. Jekel & Mr. Hydes car from hell-Please help

Hello,

I have a 94' Buick Lesabre 152k miles automatic. I have had it a the mechanics garage for about 5 days now. The well known mechanic has still yet to find the problem. As if its not bad enough I have to be seen in this car.

I need a special adapter for my car to get error codes, but luckily, no one has one! Car X,Auto Zone,Advanced Autos, Macco, Midas and the list goes on.

Whats wrong: Where to start. Ok, the car is two faced some days it would run fine and another day it wouldn't start at all. At first it was just missing and shutting off or stalling when it was idle. Once or twice as I was actually driving, like on the gas. I changed out the spark plugs and fuel filter and it ran ok for about a week then it started up again. I'm telling you this car decides when it wants to mess up thats why the "mechanic" can't fix it. The day I took it to the garage it wouldn't stay running, even in idle. I had to floor it just to get it to stay running and even then it was missing and wanting to shut down. So the next day I went back to the car in the morning and it started right up and drove perfectly to the garage. We have no clue what it could be, and I'm not expecting a correct answer. I just need somewhere to start.

Any suggestions of what it could or would be, will be much appreciated!

thanks for your time.

Has the vacuum been checked? And I think you can check the trouble light by shorting pin A to ground in the OBDI connector. There is a self-diagnosis program in the module which will count the flashing pulses.

No, I don't believe he can do that. This is a transition year and he has a hybrid with and OBD1 system with and OBD2 plug. Nothing but a professional scan tool will read the codes on this system.

Response From 3izarre

Vaccum? How would I go about that?

I have tried the paper clip idea before but it didn't work.

Response From 3izarre

I took it to AAMCO to get the error reads for only 40 bucks, pretty cheap. When I get them Monday, hopefully, I will post them.

Response From 3izarre

Ok im back,

I took it to AAMCO for a diagnostic ($40) they informed me that they got 1 error code and it was the VGR valve. I had them install a new one ($160) they said it was stuck. I picked it up after work and while I was driving the long way home, excited I had my car back, it started acting up again. Same simptons...what should I do?

Response From comnavguy

Someone has already mentioned about going to a real mechanic - NOT AAMCO. You're lucky you got out as cheaply as you did.

I have had nothing but bad experience from AAMCO, and heard some real horror stories.

Is your car running OK now?

Response From Tom Greenleaf

Frankly - I wouldn't take a shopping cart there around me but we shouldn't be bashing a whole chain that isn't right either. Each tech has a responsibility to do the right things IMO.

T

Response From Loren Champlain Sr

You took it to AAMCO? Frankly, I'm really surprised that they didn't sell you a transmission. First, I'd take it back, have them put your old EGR valve back on, and give you a full refund, including the diagnostic charge. Take the car to a real shop to have it diagnosed. Post here with the DTC(s) and we'll try and sort this out.

Response From 3izarre

Sorry on the late reply,

I've been working overtime to pay off AAMCO.

The EGR Valve is disinfectant. I saw it myself I could even get the vavle to move an centimeter. So I think it may be a couple things wrong.

I can't get the error code, I'm taking it back tommorow for a free diagnostics and inspection. I WILL be back with either a code or some results.

Thanks for your all's time,

Response From 3izarre

Good news,

I got my car back today and no symptoms on the way home, about a 30 min drive. I had them replace the fuel filter and the PCM sensor ($198 total) because they said that was the last code that would make those type of issues on my car. Here are the codes that I had him write down for me (PO341,PO342,PO1670,PO171)

I noticed the brake wasn't shaking anymore while it was depressed and the car jar just seemed more stable.

Hopefully thats all I have to fix at the momment.

Thanks!

Response From Tom Greenleaf

?? I don't understand brakes NOT shaking unless brake work was done?? Confused,

T

Response From 3izarre

I don't know any other way of explaining it,

It had vibration in the break pedal before it was "fixed" or should I not tell you anything?

Response From Loren Champlain Sr

I don't want to sound negative, but I'm not convinced that your problems are over. The P0341 and P0342 are cam/crank sensor faults. The P01671 is Quad driver 4 fault. The P0171 is a lean condition. You mentioned in your first post that you had already replaced the fuel filter. The EGR, if in fact, was leaking could explain the lean condition as well as a plugged fuel filter. But....The brakes depend on engine vacuum for the booster to work. If the engine is running bad enough, it can affect the power assist to the brakes. Even make the engine run rougher when the brakes are applied, but this is a result of...not the cause. Just what PCM sensor did they replace this time? I hate to say this, but it sounds as if they are 'throwing parts at it'. Hope, for your sake, that I'm wrong.

Response From 3izarre

So your saying,

The engine's vacuum needs cleaning?

I got stuck in traffic for about a half hour today and drove it a pretty long way with no problems.


P.S I forgot to comment....

I talked to the old mechanic (1st post before AAMCO) and asked him exactly what he did to the car. He said he didn't think it was the fuel punp, the presuur was normal. So he didn't replace the fuel filter. If that clears anything up.

Response From Loren Champlain Sr

That is good news. Let's just keep our fingers crossed. If you have any further issues, we're here to help, if possible.
Have a great weekend.

Response From 3izarre

Ummm....

The EGR valve was replaced. Noticed the shiny new part.

The PCM was replaced. He didn't state a certain PCM sensor.

I can't take it two a shop for atleast 6 weeks, bills bills bills. If it breaks, it breaks. But I can repair smaller parts myself.

I did attempt to try the diagnostics you suggested like the mass air sensor etc. but I had no clue where to find all of them. I couldn't find anything on google to help locate the certain parts.

Just whatever AAMCO did solved part of the problem, I just think it is multiple problems. As for the fuel pump, I don't trust that the old fart mechanic "Butch" did a damn thing to my car. So checking fuel pump pressure is out of my reach for now.

Response From 3izarre

I took it to AAMCO again.....lol

I had to! The car was un driveable today, it was missing when I gave the engine any gas. It wouldn't stall but it was like constant, idle, on gas all the time. I'm not going to have them repair anything. He said he would do another free diagnostics so I'm going to see what he has to say. But I'll be damned if I have them throw on another shiny part of uselessness. I also called up AutoZone today for some qoutes on the items you suggested.

Mass air flow sensor: $130ish

Ignition Control module: $30-50ish

Crankshaft sensor:50-70ish

injector: 30ish

Man I really don't have any more money at the momment. I'm so F'd.

Response From Tom Greenleaf

An engine that misses for any reason is probably going to trash your converters costing a fortune of course. Find the $ to fix that and not just throwing parts at it. IMO AAMCO is not specializing in fixing more than transmissions so get this to a regular shop asap to properly diagnose and fix. If they tell you the trans job caused this bring that up with AAMCO

Stuff gets unplugged, bumped or whatever as a trans job is invasive but every last connection need be back in place.

Again - converters are at high risk of damage with a misfire!

Response From 3izarre

Its fixed! for now.......lol

AAMCO found a bad spark plug wire and replaced them all. $53. I had them keep it for two days, it was fixed on the first and on the second day was so they could run it again to check for problems. I borrowed some cash off my pops, which I feel like crap for doing. After $300 of useless crap, the car is running good.
They also changed my donut gasket which got rid of the putter and crappy sound my car had. Now I can't even hear my engine its so quiet. I have to roll my windows down when I start it just so I don't over crank it. I have to step on the gas a little to make sure the engine is running lol. Maybe I'm just not used to a quiet car? But all looks good.

I don't understand why the wires weren't checked first but $400 its still a cheap fix. I mean, I got all the code errors fixed except the crankshaft sensor code. To my knowledge.

Thanks for helping me through this schizophrenic car problem, I know it was a ballpark problem but I thank you for trying.

I'll defiantly come back for any car troubles I have, and let everyone know this is the site to come to.

Thanks for reporting the fix. FYI - we don't get paid here - all volunteers and site runs on ads!

Response From Loren Champlain Sr

Again; These are the things I'd want to check; If you aren't capable of doing these tests yourself, take it to a shop (not AAMCO) that deals with drivability problems. Did you have them replace the EGR valve that they 'sold' you? Obviously, it wasn't the problem. What PCM sensor did they sell you the second time you went back? AAMCO is a transmission shop, and doesn't have a very good reputation with even trans. repairs. (personal opinion)
There are three or four items that are very common for this vintage; Might ask the tech if he has checked them:
1) Mass Air Flow sensor (sometimes you can tap on it lightly with a screwdriver handle, or squeeze with your hand)
2) Ignition control module (most times, these act up when hot. Can apply heat with a heat gun)
3) Crankshaft sensor (same as control module)
4) Faulty injector or harness. (Ohm test cold and hot, ohm test harness)
I assume that he has already tested fuel pump pressure?

Response From 3izarre Top Rated Answer

I hate to post again....

The car had me at hello just to break me down again today. I can tell the problem is still there. I started the car up again and it had a little miss in it. It wasn't stalling but it was missing differently then it was before. This miss was more of a faster not as serious feeling miss. But after I drove it for about 5 minutes it was fine.

I was planning on changing the oil, distributor caps, and fuel filter myself on friday, payday. And I need to clean the engine vacuum but I don't know how, I googled but to no avail.

What would you suggest I do?

Response From Loren Champlain Sr

>>I don't want to sound negative, but I'm not convinced that your problems are over<<
Please, don't take this back to AAMCO. Let's start over. I'm going to go back and read the thread from the start, and will get back to you.

Response From 3izarre

Yeh!
Thanks for your time and help.

This is probably the best car forum on the web. I posted on about 5 different forums when I first had the problem and this is the only forum I got a reponse to, so thanks. Knowing the small details really made it easier/less stressful.

Response From Loren Champlain Sr

We're happy that you're happy! Again, if we can be of any help in the future, don't hesitate to ask.

Response From Hammer Time

You can't listen to those guys. They know nothing about driveability.

What was the exact code number?

Response From 3izarre

I didn't ask,

I was just happy I had my car back! It was like a week in a half of no car, sitting at home, bored as........I DIDN"T KNOW! jk lol

Imma call'em tommorrow, I'll ask for em'

Response From 3izarre

CRAP!

I started a new thread cuz my reply wasn't showing up! my bad lol

Response From 3izarre

EGR*

Response From Hammer Time

If you have a check engine light coming on, then that's where you have to start. Just because the free service places can't read the codes doesn't mean it can't be done. Your car is in a transition year between OBD1 and OBD2 so it's not 100% of either. That means it can only be read with a professional scan tool which any reputable repair shop should have. It just won't be free.

Response From 3izarre

Thanks for your reply,

I don't have a check engine light, even though I know it should be on. Probably just broke.

I agree with taking it to another garage or service station, which I'm planning to do at the end of the week. I'm trying to be patient.

From the symtoms I'm expierencing what do you think it could be? I understand it could be numerous things, but you think its electrical or maybe something messing up in my fuel system, engine trouble?

Response From Loren Champlain Sr

Response From 3izarre

Those symptoms sound correct,

My car always started up in the morning (cold) And would act up when I would get off work around 2:00pm (hot). Thanks for the suggestions, now I have somewhere to start. The mechanic said that he tested the fuel pump pressure, he said he didn't think it was the fuel pump.

How do I tell my mechanic how to do his job? lol just kidding.

I guess I'm going to get to work on this I'll report back with good results hopefully.

Thanks again, 3iz

Response From Loren Champlain Sr

You may want him to check the CTS (coolant temp sensor) as well.

Response From 3izarre

Ok,

Response From Hammer Time

I gave you a systematic was to isolate down the cause. If you follow that, you will find the source of the problem.
