behind the glove box on the passenger side. but ive only replaced 2 pcm's in that body style in all my years. are u sure thats whats causing your problem?

the piece you are referring to is a resistor of a specific value, witch compares to a value hardwired in the engine management computer, yes this can be the culprit, make certain the contacts are clean, use some fine steel wool to clean or an ink eraser is good to, there can also be a fault in the contacts in the key hole, especially is someone tried to steel you wheels inserting incorrect keys can also danage the contacts, do you have a shop manual for your ride ? let me know

How old is the battery?

I would check the power steering fluid level first and if its down repair the leak and recheck to see if its cured if there is no leaks and the level is fine ..Remove the serpintine belt and see if the pwr steering pump pulley pulls off. I have seen the pump shafts break and appear to be fine but they will pull out of the pumps...Good luck hope this helps..

Check the neutral safety switch,if it is o k,then replace the ignition switch,Not the key cylinder,but the electrical part.

NO, its not the filter, although it should be changed every year. It needs top be checked by a qualified repair shop. There are too many possibilities of what it COULD be. TPS and IAC are 2 that should be checked first. but you need special tools to check them.

Get some dryer sheets and moth balls and put them all over where the mice are.They will leave.They don`t like the smell.I can`t tell you where they are getting in because I don`t know but you will have to look around the vehicle and see if you can find a hole.It does not take a very gig hole either.Hope this helps.Good luck.

I would first make sure you in drive when shifting, don't go by the dashboard (you could have some slop in the shifter cable/rod) I you shift down 3 gears from park you should be in D and see if that still does the same, if it does your shift solenoids may be bad or worn clutch packs in the tranny.

Based on the information you have given to this point, I am just going to give you a few possiblities. Have you had a tune up done recently? Air filter been checked or changed? I am not in any way trying to sound sarcastic so I apologize if I come off that way.Those would be my first things to inspect if I were ask to look at your car. I would also check fuel pressure and inspect the fuel pressure regulator.I would consider these things and go from there. I Hope this helps you but please let me know if you need more information on what to do next but I may need some more information at that time also .

The most common problem is the crank pickup going bad.
If you have never changed this sensor do it now....you will have to change it soon anyway.
Not expensive........it causes a lot of problems and fails often.

Do you see a check engine light come on when the car tries to stall?
Hopefully you do....it will help with a quick diagnosis's of the stalling problem.

How do you bypass the chip that's on the key?

1991 Oldsmobile... | Answered on Oct 19, 2009


If the blower motor,or the cooling fans are staying on,then it is a relay stuck.Find the relay,by removing relays one by one,replacing them back as you go.When the relay is unplugged,the fan will go off,If you put it back in,it will probley not come back on unless you turn the ac back on,then it will do it again.Replace the relay with a new one.I hope this is helpful,let me know if it is.
