Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I would start with doing a couple of things that may help you resolve this concern, first disconnect the negative battery cable and then take some carb cleaner and a soft cloth and give the throttle body and plate a good cleaning and while doing so also take some MAF cleaner and give the Mass air flow sensor a good cleaning and then reconnect the cable , start the engine and allow it to idle for 15 to 20 minutes to allow the computer to reset. After doing this, take it for a drive and see if the problem has cleared.
The throttle body consist of it and the TP sensor, you do not need to remove it to clean it. It can be cleaned on the car.
Be sure to clean the throttle body as well and when doing both also disconnect the negative battery cable before you do both.
So are you saying that took care of the stalling ?
Bruce is the check engine light coming on and if so are there any fault codes?
Im not sure where to go with this, I was assuming you where working on an 1994 Grand AM that you have listed. Because its a conversion its going to need some hands on testing . I can open the post back up for you and perhaps someone else may have something new to offer.
