Hey guys heres anouther problem Ive having with this heap....lol

I got a brand new battery for the bad boy and went to start it and now the car seems to idle very poorly, is this another common problem with the GTP? this car is just getting on my nerves now... lol seems like you always need a Straw to get something to work either pull your key out you need a straw or to get my windows to roll down properly you need a straw, my room mates are getting upset because I keep taking straws...................

- thank you, Mel - 2002 Grand Prix GTP
 


Did you clean the connections really good? also make sure the terminals are tight. And what do you mean by straws getting stuff to work?
 
How long was the battery disconnected? Most likely it cleared out the ECM and it needs to relearn everything. Take it for a normal drive (not romping on it) for about 15-20 min. and then see if it runs better. If it does, then you can take it out and run it harder. I usually take mine on a road that varies the speed limit so it can get reading at different speeds/throttle inputs to give it a better idea of what's going on.
