Question From doanuts on 1990 mazda miata

I need help. My 1990 mazda miata check engine light comes on while driving then when i let off the gas it goes away

Response From Sidom

Have codes read & come back & post the numbers.....Most parts stores will do this for free

Response From doanuts

The engine light doesnt stay on will it still show a code if the lights not on? It only comes on while driving. But i let off on the gas pedal and the engine light turns off. This happens time to time and sometimes multiple times while driving. Iv never owned a miata and jus bought this one a couple days ago. The speedo says 390,xxxmiles but the engine dont look like thats on it or even the car itself

Response From Hammer Time

Yes, the code should be stored in memory but you may have to pay a shop to do that one since it's OBD1.

Response From doanuts

Ok sweet thanks ill get back with the codes if they dont kno what it is.. do you know what the ticking noise in the top end might be? It isnt always there is comes and goes too

Response From Hammer Time

You'll have to make it louder. I can't hear it.

Response From Discretesignals

That one you can retrieve trouble codes without a scan tool. There is a diagnostic connector under the hood. Jumper TEN and GND together in the terminal and turn the ignition on. The check engine light will flash the code(s) in two digit format.



Ticking noise could be from the valve train. The hydraulic lash adjusters (HLA) are supposed to take up the play in the valve train as things wear. With the mileage the valve train is probably worn out or you could have HLA problems. Change the oil and make sure you use the correct viscosity (10W-30) to see if that helps.

Response From Discretesignals

Code 12 means the engine computer detected an open or short in the throttle position sensor circuit.

This means you need to monitor the throttle position sensor voltage to see if you have a defective TPS, a wiring problem, or a computer issue.

To check the throttle position sensor, you need to use a volt/ohm meter.

This video goes over TPS diagnosing. The TPS operation is the same on most vehicles.


Response From doanuts Top Rated Answer

I wud like to know if fuel injector number four, cracked and flooding piston four, would also make piston number 2 not work

Response From Discretesignals

You have too many threads open on this vehicle for the same problem. We are telling you what to test and your not giving us any feedback. With the other threads, your making it confusing and leaving other hanging in the wind. Please keep it in the same thread.

Response From doanuts

Sorry m jus getting use to this site and m kida comfused myself.. i dont have access to an ohmeter can u use one in autozone? Sorry fer the comfusion i jus bought this car m jus tryn ta figure out what is goi. O. With it. And need to learn this site better. Thank you for your help if u have an answer to the last question ill only post on this one link. Can u delete one after youve posted it?

Response From Discretesignals

Is that what happened? You have a leaking injector on #4? Did you see if the regulator is leaking?

Is #2 cylinder flooded also?

Response From doanuts

I did test with tube from intake manifold off nothing squirted anywher from the regulator. Yes i pulled all plugs and plug 2and 4 wer wet with gas the others were dry. When i pulled all the injectors out the one for piston/plug 4 was cracked on the end. Injector 2 had a scratch idk if its a crack. So 2/4 are getting flooded 1/3 are fine and still igniting. I checked for spark from the coil pack and it was good.

Response From Discretesignals

I don't think that a cracked injector in #4 would flood out #2, so it probably wouldn't be a bad idea to replace them both.

In fact, if you have the money, it probably wouldn't be a bad idea to replace all four injectors just in case #1 & 3 let loose later.

If the injectors were leaking fuel into the cylinders, its possible that those two cylinder could be washed out. That means they may have no compression, so you'll have to squirt a little bit of oil in those cylinders to get the compression to come back up while cranking the engine with the plugs removed, all injector connectors unplugged, and coil unplugged.

You don't want gas or spark going on while your trying to restore compression while cranking the engine.

Response From doanuts

Yes hopefully this is the only problem i had ordered some racing injectors all four

Response From Tom Greenleaf

Shane: I suggest staying OE for replacement parts or could confuse the fix - not certain but may open Pandora's box requiring other alterations to accommodate doing that. Yes it's now an old car but not old enough IMO to fool with things aftermarket, performance or other things,

T

Response From doanuts

Hey guys i have two questions..1 is when i put cold air intake what happens with the mas air flow sensor plug thats pluged into the stock intake box? What do i do with it and with it not pluged in what will it do?.....2nd i need new wheel bearings in front my car is the 1990 base model, does it have ABS? the bearings i found come together with lugnut bolt hub assembly i need to know wether my car has abs or not....thank you!!

Response From Sidom

You need the MAF sensor, the engine won't right without it....If that kit is for that model, there should be a way to mount it in to your new system. That part can't be eliminated.

For your wheel bearing, just look at the dash. There should be an ABS light that comes on for a few seconds & then goes out when the car is started..... Or you could just look at the hub assembly, see it there is a sensor with a wire going to it, also there should be an tone ring on the axle....

If you have any issues with the bearing start a new thread......

So what was the final outcome with the running problem??? Did you get it fixed??? What did you do???

Response From doanuts

Thank you. Ther was a cracked fuel injector and the wire harness for the fuel injectors was bad. As for the white smoke i had changed the oil and put the 5 litter oil change jug into the engine when the engine only takes 3.2 litters off oil. Changed oil again runs great. Still havent figured out the check engine. It blinks once then twice im taking that as a 12 but anywhere i go they cant figure out what it is.

Response From doanuts

I did the thkng and it blinked once then twiceso m guessin thats a 12 and the book at auto zone said it doesnt apply to my car

1998 Mazda 626 running ruff, check engine light on

Question From plsmoothy on 1998 Mazda 626 running ruff, check engine light on

Hi guys. It's me again with yet another problem with my '98 Mazda 626, 4 cylinder 2.0 with 139,000 miles.

A couple of days ago I ran my fuel level down to the lowest point I have ever dared to. I seriously thought I was gonna stall out somewhere. Got to the gas station, filled her up and I was on my way. A while later I noticed that when I was idle at a light, the engine sounded like it was misfiring or something. It wasn't running rough, it would just kinda pause for an instant and then continue. It only happened when I was idle. As I continued driving it got worse. It finally reached a point where it got really bad and then the check engine light came on and the car started running really rough. Also, the exhaust smells different. It starts up just fine and it doesn't stall out ... it just runs rough.

Broke out my Haynes manual and did some troubleshooting. The spark is being delivered to all 4 pistons. Removed the electrical connector to fuel injector 1 and there was no change at all in the running condition. Removed the electrical connectors to fuel injectors 2,3 and 4 and the car practically stalled out. Applied auto stethoscope to fuel injector one and I could hear it ticking away. I removed the electrical connector to injector 1 while the stethoscope was applied and I could hear it come on and off. Tested the other 3 injectors and I could hear them come on and off as well. It seems like fuel injector 1 is working but it might be totally clogged up. Am I on the right track? If so, is that something I can repair myself?

As always, you're advice is greatly appreciated ... thanks!

Response From Loren Champlain Sr Top Rated Answer

plsmoothy; Sounds like to me that you are on the right track. As I'm sure you are aware, water is heavier than gasoline, as is debris. When you let the tank get that low, it's very possible that you've sucked up something from the bottom of the tank that has been lying in wait. It's also entirely possible that it is completely coincidental.
You can try injector cleaner, but if it's plugged, will probably take more than just the stuff you can pour into the fuel tank. There are a couple of possibilities, if it is actually plugged. You can have an injector cleaning done or remove the injectors and have them cleaned. And, keep your fingers crossed. You may want to do some diagnosing, first, though. If the injector is plugged, that means no, or very little, fuel is getting to that cylinder. A gas analyzer would show low HC if that is the case. If fuel IS getting to the cylinder, you'll see high HC. Also, ohm check each injector. Just because it 'clicks' doesn't mean it's actually working.

Response From plsmoothy

Loren ... just got off the phone with a mechanic who told me that when injectors are as old as mine (139,000 miles) I should just replace them and not bother having them cleaned. Is there any truth to that? I started checking out prices on ebay and I've found a wide range of prices. How do you feel about rebuilt fuel injectors? Would it be unwise to buy inexpensive injectors? Thanks again.

Response From Loren Champlain Sr

plsmoothy; We use a machine called "Motor Vac" injector cleaner. The vehicle's fuel supply is 'disabled' and the engine runs off of the machine. The chemical goes throughout the entire combustion system and cleans the fuel rails and injectors. It takes about 1.5 hrs and does an excellent job. I've personally seen many plugged injectors come to life during the process. We get a lot of customer feedback, almost always 2-3mpg improvement and better performance. A lot of them will bring in their other car for the same thing because they were so impressed with the results. We recommend doing this every 30-40,000 miles. So, to answer your question, no I wouldn't 'just' replace the injectors. Yet. The cleaning process should be done, regardless. If it works, great.
If it doesn't, it needed to be done, anyway. As far as reman. injectors, the only time I use them is if new ones aren't available. Personally, don't like reman. parts in most cases. If you do end up replacing them, I'd recommend buying new ones from the dealer, NAPA, or CarQuest. Not something you want to skimp on, because you only want to do it once.
Sorry, probably too much information.

Response From Guest

Loren ... thanks for the reply. A couple of follow up questions. Can I buy a gas analyzer or should I take it to a local shop? Also, when you say ohm check each sensor, do you mean check it with a voltmeter? I'm not very knowledgeable when it comes to auto electrical.

Response From Loren Champlain Sr

Exhaust gas analyzers are very expensive pieces of equipment. Several thousand for a 'decent' one. Check for resistance readings with an ohmmeter.

Hi community. I drive a '98 Mazda 626LX 2.0L 4Cyl with 140,000 miles. The car idles at approximately 650 RPM. At this RPM, I get an intense vibration in the engine and throughout the car. Here's what I've done in an attempt to eliminate the problem. 1. Changed spark plugs/spark plug cables. 2.Checked engine compression... compression good. 3.Removed fuel injectors and had them ionically cleaned. 4.Checked for error codes ... none found. 5.Replaced fuel filter.

At this point I'm considering changing the motor mounts. Before I do that however, I want to increase the idle speed by 100 RPM or so. Can anybody shed some light on how to go about in doing this? Also, any other insights are greatly appreciated.

Thanks

At that mileage it is very possible it's your motor mounts. To verify this if you put a floor jack under the engine & slightly jack up engine (with a piece of wood or something so as not to damage the pan) to take take the weight off the mounts & your vibration goes away( while the engine is running), then it's the mounts for sure.....

Response From plsmoothy

Don't want to beat a dead horse here but is there absolutely no way to reprogram the computer to increase the idle speed? An increase of 100-150 rpm's seems to make all the difference in the world.

Thanks again.

plsmoothy; The idle spec for your car is 550-800rpm, so as Hammer stated, it is within specs. And, as he said, the idle speed is computer controlled. If the engine is running rough and is within idle specs, you have an underlying problem that is causing the roughness. Changing the motor mounts won't fix the roughness. May even make it more noticeable.
Have you had the injectors ohm checked? Have you cleaned the throttle body and IAC? Compression test? Valve clearances? So many things can contribute to this.....No easy answer.

Response From plsmoothy

I'm in the process of cleaning the throttle body and idle air control (AIC) now. I noticed there is quite a bit of a tar like substance in the intake manifold. Should I clean the intake manifold since I'm already in the vicinity?

I took the advice of Sidom and loosened up a couple of the motor mounts, put a jack under the oil pan and lifted the engine. The vibration felt pretty much the same. Does that prove that it's not necessarily the motor mounts.

In addition there is something that I forgot to include in my original post. The idle gets rougher when I turn on the Air Conditioner. The vibration gets really intense.

As always, your help is greatly appreciated.

Response From Sidom

Sounds like the intake is pretty dirty. Cleaning the throttle plate is good but most shops offer services that run cleaning solvent thru the intake & also disable the fuel system & run it thru the rail also to clean the injectors.

The method I told you about you don't loosen any of the mounts, just put a just under the pan w/wood & a couple of pumps to support the motor & run it. On the ones I've done that had bad mounts this would either eliminate the vibration or make a noticable improvement.

Now I'm assuming you've check all the mounts & none are broken. This method is only to check mounts that have hardened & are transmitting the engine vibration..

Hi there,

I have a 1993 and the same problem. To adjust the idle the computer needs to be re-adjusted. Place a wire between TEN en GND inside the diagnoses connector. Adjust the idle with the flathead screw on the right top side of the t throtthle body. Rotating counterclockwise will rise the RMP. Turn the car of and remove the wire. I have tried it and the RPM are now 950 rmp but it is still a little bit rough. Also cleaned the EGR valve, clean the IAC valve, cleaned the injector etc....

Response From Loren Champlain Sr

Cleaning the throttle body and idle control motor may help.

Response From Hammer Time Top Rated Answer

Loren, The idle is right where it should be. He just thinks if he runs it higher, the vibration will go away.

Response From Hammer Time

The idle for that car is entirely controlled by the computer and not adjustable in any way.

If your getting a vibration, the motor mounts will likely cure it.

1999 Mazda B3000 lacks power

Question From briannaragon on 1999 Mazda B3000 lacks power

The trucks has been sitting in a garage for about a year. It runs well in first 3 gears. Severly lacks power in 4th and 5th. I have regapped the plugs, put octane boost and Lucus fuel injector cleaner in and filled it with mid-grade gas in. I have also replaced the fuel filter. Still having the same lack of power issues. I don't have any signs of a blown head gasket. What else could it be?

Response From Tom Greenleaf Top Rated Answer

Sorry to be so late for any response and not sure at all. It may benefit from professional injector cleaning called "Motor Vac" as a guess. IMO Lucas is a waste. If fuel problems SeaFoam is much stronger but use anything in moderation. Don't put much faith in the magic in a bottle stuff for much of anything,
