I have a 93 Cadillac sts seville with the 4.6 V8 Northstar. When I accelerate the car runs fine, but when I let off the gas it surges or****** as the idle goes down and the car slows down. A couple of times the car stalled when in reverse. I replaced the plugs. Any help would be great.

If you'll pull the codes and post them, I'll look them up. They'll most likely tell what's going on.

Possible EGR sticking, and could even have a deceleration misfire.
