I left my dome light on over night and drained the battery. After jump starting it the next day I noticed right away something was wrong with my 90 lumina 3.1. When you start it up the idle goes real high, then realllly low, it dies out sometimes but most of the time plains out and is fine as long as you're in park.
When its in gear it drives fine down the road, but when you take your foot off the gas it begins fluctuating, and once died while coasting down the road. At stop signs it fluctuates hardcore and pulls the car forward at the high end, sometimes stalling at the low end.
Did I fry the computer---or some sensor??? Is this going to cost me big bucks????
PLEASE HELP!!!!!
