Re: Runs Rough

Yes, it could be a clog in your injectors.

The only other thing i can think of is a bad Ignition control module (Located under the coil packs), however a bad ICM typically shuts the car down completely....

But....my brother''s car w/ a 3.8 in it had good coils, and a partially bad ICM....so if the injecter cleaner doesn't help then I'd suggest to try to pull the ICM and have it tested at Autozone or O'riely (free!).

If it tests good then the only other thing I could think of would be a weak fuel pump...

good luck. One more thing, if you still have problems, try to post in the olds 88 forum (more people visit, plus the cars are almost identical).
