Have a 1991 vert. The DME was unplugged for about 5 minutes. Drove the car the next day about 20 miles and ran fine. On my way home at a stoplight, my idle became slightly erratic. Stopped at a restaurant to have lunch and when I was leaving, the car died in reverse and had a CEL, started back up fine. Drove home, turned the car off. For the first 5 minutes the car idled very rough and the check engine, abs, park brake, and battery lights were on and surging with the idle. When I revved the car, it was very rough but the CEL would go off and when it returned to idle, the light came on. Now the car will not idle at all...it will run about a total of 2-3 seconds and die.
The IAC has been unplugged for about 3 weeks and the car has ran fine the entire time. I'm assuming low battery voltage or a vaccum leak somewhere?
Anyone else have any ideas or experience with these symptoms? I've tried letting the car sit overnight and it still just will not idle...
