EGR Valve 96 Buick Regal

Showing 2 out of 2 Posts
Question From regalcustom96 on EGR Valve 96 Buick Regal

I have a 1996 Buick Regal Custom 3100 that I've been driving for a few years as a "no car payment" car. The check engine light has always been off and on, the code pointing to EGR insufficient flow. I've been in the bad habit of getting it cleaned right before I get an emissions test to clear the light. But it always comes back on within a day or two.

I'm finally buying a newer truck, looking to sell the Buick. Do you think buying a new EGR valve and slapping it on would fix the problem buy-and-large? I know there are other issues like the lines in and out, etc. But for $90 off the shelf, it would be worth it to just try and change it out instead of going through a shop. I've taken my old one off to try to clean it, so I'm fairly sure I could change it out.

Any thoughts are appreciated

Matt

Response From Discretesignals Top Rated Answer

You probably have a clogged EGR passage in the intake manifold between the EGR valve and the inside of the intake manifold. That is a pretty common problem on those.

Best way to clean it is to remove the throttle body and EGR valve. Then clean the passage out with a coat hanger and carb cleaner. Rifle brushes work too. Replace the EGR gasket and throttle body gasket, clear the codes, and see what happens.

EGR valve causes Check Engine message

Question From vtech on EGR valve causes Check Engine message

Hi;
I have a 1996 Buick Park Avenue- not supercharged. Specs for an EGR valve ask whether 8th digit of VIN is a "K" or a "1". What is the difference? Some sources say there is no difference some say it is important.

A new EGR from Buick dealer is around $350 so I tried a used parts place and they said an EGR from a '98 Olds would work fine. I tried it, but although the car runs perfectly, it caused the Check Engine light to come on.

Should I return the part and look for another? What other vehicles would have the same EGR part?

Can I use the '98 Olds EGR and a piece of black electric tape? I've heard that is the fix for many of these codes.

Response From Indytech Top Rated Answer

Get the codes, and let us know so we can help you out
The 98 olds has the same engine EGR valve is the same
when you get a code for the EGR does not always mean its the valve itself

Ignition Problem - Random

Question From stevef7896 on Ignition Problem - Random

1992 Buick Century Special
2.5L
130,000 miles

My problem is random. 75% of the time it starts with no issue, runs fine, starts again after making stops. After several hours of sitting, the car will sometimes not start. It turns over, has normal tempo, I hear the fuel injector run, but will not start. I have replaced all spark plugs and wires and checked the resistance of both coils which were fine. I have engine codes 13 and 32.. oxy sensor (which I replaced) and a generic EGR system error.

At this point I am looking for advice, as I'm still rather new to this. I was thinking I would take my ignition control module to autozone to have it tested. Is this a likely cause, or am I going the wrong route?

Thanks in advance for helping to ease this drawn-out headache.

It sounds like you might have a sticky EGR valve

Remove the EGR valve assembly and clean it out with carb cleaner. Make sure you clean out all the passages. Make sure you use a new gasket when you put the EGR valve back on.

That would be where I'd start.

Response From stevef7896

I've had mixed answers on whether the EGR valve could be causing the starting problem, so I did try to clean it out and used WD-40, but if you think that could be the whole problem, I'll get some cleaner and give that shot. Thanks.

1992 Buick Regal - Error Code 41

Showing 4 out of 4 Posts
Question From J_Duchscher on 1992 Buick Regal - Error Code 41

I have a '92 Buick Regal - 3800. Recently my check engine light has started to go on and off. Also my car has picked up an occasional hesitation (runs fine most of the time, but hesitates a little and then comes out of it). I checked the codes and came up with error code 41 (which is the cam sensor signal). I took the car to the shop and they replaced the cam sensor, timing chain, magnet….took the car out and the same thing. I ran the car for awhile and took it back to the shop and they did a few more things and car runs the same. This has been ongoing for a couple years. Now my car died out and want run. I’m tired of spending money at the shop and not getting results. Any ideas what it might be…ICM, Coil Packs, ECM, EGR Valve???? Any assistance would be appreciated.

Response From nickwarner

believe it or not, this is a good thing that it wont run. Find out whats missing, spark or fuel, and we can narrow it down from there. Now that its not an intermittent its easier to find

Response From J_Duchscher Top Rated Answer

The spark plugs have spark when trying to start. Also, the fuel pump is working, but I'm not getting fuel to the motor. Some additional information. After the car sits for an extended period of time and I try to start it, it does start for a split second and then dies and won't restart at all. If I leave it sit for awhile the same thing. Something else to note. When the car was in running condition, the colder outside the better the car ran (I'm talking like below 20 degrees), the warmer the air temp the more it picked up a hesitation. Hope this information helps.

Response From johnparker

have tried cleaning the carbon on the spark plug? if not then try it, i think i will help!

2005 Buick Century codes p1404 and p520

Showing 3 out of 4 Posts | Show 1 Hidden Posts
Question From robertmt on 2005 Buick Century codes p1404 and p520

Please be patient while I explain what I have done with this vehicle. I got a service engine light about a month ago which pointed to the EGR valve. I changed the valve and the light went off for a time. Then I get the light again, I have a code p0171 suggesting O2 sensor. I changed the O2 sensor on the exhaust manifold to no avail. Ordered and replaced the downstream O2 sensor near the Cat and all codes were gone. Success! For a day.

I then find that the water pump is leaking so to gain easy access to the pump, I reposition a large wiring harness and pushed it up toward the windshield while I replaced the pump. After that, everything is fine again, and today we have a strong smell of fuel from under the hood, along with codes P1404 AND P0520. It seemed I may have disturbed some connections somewhere, since these two codes do not seem to be related, but cannot find anything out of place.

After the fuel odor dissipates, the engine runs great, no hesitation, no stalling no shaking. Just the engine light on!

Thanks in advance for any ideas!

You're dreaming if you're expecting a downsteam sensor to resolve a P0171. It has absolutely nothing to do with that sensor. It's a lean code.

The P1404 could be due to carbon chunks being broken off and getting caught in the valve.

The P0520 is a problem with the oil pressure sensor circuit.

Response From robertmt

Well that was my understanding too, but out of desperation I changed the downstream O2 sensor and the light went off!

Thanks for the reply.

Response From Hammer Time Top Rated Answer

Changing the sensor didn't cause the light to go out. That sensor has one purpose and one purpose only and that is to monitor the efficiency of the Catalyst. It has no relationship to fuel mixture.
