1987 Cadillac Sedan Deville. When driving the service engine light will come on and then the car will accelerate. What is up with this car? Can someone help?:confused: :confused:

Dirty Throttle Body? Faulty ISC motor? How about the trouble codes? Depress Warmer and Off on your climate control until it shows the codes. Wright them down. Compare to ones posted on this site (sticky ones).
