Advice for rough idle???
Car is a stock '91 coupe with AT. Symptom is rough idle after warm-up, although RPMs are right at 800 - 850. Also hesitates to drop down into lower gear unless accelerator is pushed decisively. It just sort of bogs down in OD without a lot of acceleration.
Anyway, I can take it to a dealer for a diagnosis, but before I do I thought I would at least get some insight from forum members. My reflections tell me it could be fuel pump, timing, or fuel pressure. Could also be a vacuum leak. Anyway your thoughts are appreciated.
