I have a 1994 Cadillac STS. My problem is my car runs great until you put in gear. Thenit starts running rough intermittantly, somtimes for a second somtimes for minutes. The Check engine lite comes onor flickers as the problem comes andgoes. I loosepower, it sputers, and somtimes stalls. No codes are being left. Trany fluid good. Any ideas! I need this car running now so that I can get to work tomarow.

 

check fuel pressure and grounds at engine. If you disconnected battery you need to relearn idle.

 

It runs great no stumble no nothing until it goes in gear

 

out of couriosity... can you read fuel pressure thru the info I can retrieve on the instrument panel?

 

no.
