1991 Chevy Corsica 2.2l

[DALE FERGUSON]

Car runs fine , if it is damp or humidity levels high or it rains out it wants to stall out or idle rough. usally dies or stalls out. it will start up again no problem but it will continue doing the same thing. if it is dry or cold out side the thing runs great.any suggestions?

If it has a distributor cap, i would check to make sure water isnt getting in there and messing up the spark. Same with the various electrical connectors under the hood, make sure water isnt getting in them somehow.

i had the exact same thing on my 91 corsica 4 banger


never did find out what it was, though a mechanic figured somethign to do witht he coils, not sure though

but good luck!

I would check the vacuum lines. If you have a hole or a cracked line, moisture could be getting into the system.

The coils on my 3.1 cavalier had a bad habit of failing. Only one would fail (2 cylinders) and make it run rough. You can take a volt meter and check to each of the coils. A Haynes book has the specs.

it sounds like a secondary ignition problem, check wires, plus coils thing like that...
