Question about 1999 Pontiac Grand Am GT

My 1999 Pontiac Grand Am GT keeps stalling out while driving

The vehicle will stall out after about 30 minutes. The old computer was replaced with a used one. It still does the same thing.
ABS light will come on and off. The gas gauge will give different reading after it stalls and the car is restarted.
Sometimes it will start back up with no problem other times you have to keep cranking on it to get it to start.

    I have the same problem . My 1999 grand am gt will stall while driving. At first it would happen maybe once a month but now it happens more frequently, such as every every day , but it will stall say, 3 times in a row then it won't do it again . It stalls when i take my foot off the gas ( usually on a turn). I have changed the fuel pump , fuel filter , idle air control valve , and the crank sensor . I am going to take it to the dealer to reboot( reprogram) the computer . Any help would be greatly appreciated .

There are 2 possibilities off the bat i could think of. first suspect would be fuel pump. they can be very intermittent with gradual progression. next common problem for this symptom would be security issues. make sure youre using genuine GM key. ck body control module for codes. code b2960 in HISTORY would indicate faulty bcm. there are also issues with invalid "passlock" data whcih is a security sensor attached to ignition switch. tricky to replace and reprogram so be careful.

Why does my 99 pontiac grand prix gtp supercharge keep stalling


I would check the idle air control valve before replacing anything.
The computer regulates the idle speed by controlling the amount of air entering the intake thru the throttle body.
The valve could be faulty, or the throttle body can be gummed up.
Is the check engine light on ?

My 1999 grand prix stalls and dies at stops.


My Pontiac Grand Prix is also a 99, it has 216,+ thousand miles on it, it runs great, idles good, I need to replace the oxygen sensor tho as it shuts off on me while driving or sometimes coming to a stop. You might try checking the fuel filter and pump as well.

2000 Grand AM GT Shuts off while driving


What you should do is check for spark when the vehicle stalls.If you have no spark then you probably have a bad ignition module.The other thing is You didn`t mention if the check engine light is coming on.If it is then have the codes read.Even if it is not you should still check the codes.Sometimes the computer will have a code and the light will not come on.This could give you a clue as to what could be causing the engine to stall.You might also want to check your fuel pressure just to make sure it is good.The pressure should be 52 - 59 psi.Hope this helps.Good luck.

My 1992 Pontiac Grand Prix will not idle


the computer probably need to relearn the idle-try driving the car for 20-30 minutes,i u can. if that doesnt work,try keeping the car in drive at idle speed if possible without touching the gas pedal-even though it might stall,see if eventually the idle will raise up on its own.hope this helps you.

2005 g6 stalling


I would suggest checking your wiring (core wire on the distributor, plug wires and the negative battery ground) I would imagine that the forward motion of the vehicle is possibly making your wires lose connectivity and making the car stall. Just a thought though.
