Engine Performance problem
1990 Other Cadillac Models V8 Automatic 129656 miles

My service engine soon light was on and then went off drove about 50 miles stopped at red light and for the next 25 miles won't go over 30 mph. What could it be?

you first have to get the engine scanned to see what set the code. that could be causing your problem. If it doesn't fix the problem, then have apro look at it due to too many things from a partially plugged fuel filter to a clogged converter.
