Odd idling
Ok, here goes. My 92 Bonne SE is having some issues. And I have looked in previous posts for the problem:
It is idling at about 800 rpms and then shutting off. I've changed the fuel filter, which helped a little, its not stopping while I'm driving anymore. So I'm thinking IAC, and PCV valve, but I can't find the PCV on my car. I also plan on changing the O2 sensor
Fuel pressure is fine, all ground connections are good. Anything else I should be looking at?

Not sure on the 92 but on the 96 the PCV is part of an assembly with another sensor on the left side of the motor, attached to the upper LIM plenum( big black plastic bit). On my 96, you unhook the senson wire, push down and twist to remover the sensor( sorry not sure what the name of the sensor is) and the PCV valve is nested inside this assembly. Not too sure about the 92, but I hope this helps..

Not to sound like a total retard here, what is a MAF? I mean I know a little about cars, do most of my own repairs, but what is it and where is it?

Mass Airflow Senson...its located on the right side of the engine on top of the throttle body ( silver metal thing next to the black plastic tube that attaches to your air filter box). It has a wire harness plugged into it. it will also have a letter and number code on top of it in the plastic.

I think the MAF may be the problem. I took off the conecter fromt the filter to the throttle body and put my hand up there and it dies instantly. So is that a good indicator?

Cleaning the small delicate MAF sensor wire is a good place to start, although I would use rubbing alcohol on a Q-tip instead of brake cleaner. That wire is delicate and you need to be very careful, but a dirty MAF sensor wire can cause poor idling.
Remove the MAF sensor from the throttle body (usually a black plastic piece held onto the throttle body with 3 screws). once removed, look in the hole of the stem of the sensor (the part that extends into the throttle body) and you will see a wire filiment. Dip the Q-tip in rubbing alcohol and carefully wipe the wire free of debris.

I don't believe the wire can be replaced, and a new MAF sensor could cost over $100. One from a junkyard would be cheaper, but again, it may or may not be working, and I am not sure what years are interchangable.
Honestly, you can clean it.....just be careful and don't put a lot of force on it. Just use light pressure and the properties of the alcohol to disolve away the grime. It may solve or at least help your problem. If it doesn't then we have eliminated that as a potential issue. You can do it!
