1990 grand prix 3.1 car originally stumbled when transitioning from acceleration to cruise and would stutter real bad, I had to either punch through it or let off the accel. and come back on it slowly. Then while driving fast down the freeway the car lost engine power but was still running could control steering just no power. Stopped and tried to restart etc.. would start and idle rough then just die upon accel.. Came back approx. 18 hours later and she started fine and ran good, not much stutter like before drove a few times nice and easy but also got up to 55-60mph. Then today I go to get on the freeway and BAM! she goes dead again did't get much past 60 if at all, had to giver and llittle to gain speed when it happened. Now she just sits. What should I do.

possible engine coolant temp sender

SOURCE: Car starts fine..Idle is fast...stalls after car warms up

Check for vacuum leaks. Also try cleaning the ISV.


If that doesnt work go to vwvortex.com and post your issue there

SOURCE: starts with boost then car dies after 1 km and won't start

once the car is started it runs off the alternator .. so even if your battery is bad the alternator will still run the car .. so it looks lilke your alternator is bad .. when you jumped the car you charged the battery a little but not enough to keep it going since the alternator is not charging . if you hook up a charger overnight then you might be able to run it long enough to get somewhere (garage) .. try to drive when you dont need lights .. those will run down the battery in a short time .. if you have a volt meter then the battery should read about 13.8 to 14.2 volts when the alternator is working properly (car running) .. if it reads lower (like 12volts or less) then the alternator is not charging .. some auto parts stores will test your system free ..

check and clean your air idle control servo motor usualy located on or right next to the throutle body. check your map sensor also. the iac. is bad about getting gummed up and sticking closed or wide open, check that your air breather tubing is hooked up good no cracks or tears. could be messing with your mas air flow sensor which plays a major role in air fuel mixture and computer controled temp sensor could be failing it acts like an automatic choke. a scanner could help you out alot if you can have a local shop scan it.
