please help, i have a 1993 grand prix with a 3.1. It ran great untill i left the lights on and it got down to 20 below that night. when i tried jumping it the next day it would not start. after fully charging it, i did get it to start but it idles very poorly, and almost acts like it is missing. With the car in park it runs fine with the gas pressed, but as soon as a load is applied, it acts like it is missing again, and vibrates, and just has absolutely no power. the plugs are new and i replaced the wires. no change. any ideas:confused:

Might have to do an idle relearn. Do a search on the forums, you'll find something.
