Asked in Cadillac DeVille
When I start my 1992 Cadillac Deville the engine runs at high. When I turn my car off the gas pedal pumps itself for a couple of minutes and there is a clicking in the engine. Please help?
The ISP Idle Speed Control controls the speed of the engine and may need to be replaced.It is located top front of the engine next to air intake and has a stop screw sticking out that sets the idle electronically. The clicking is normal and is probably coming from the ISP . My 95 Deville has clicked since it was new.
