Question about 1992 Cadillac DeVille
Sounds like the ISC ( idle speed control ) motor is being told by the computer to extend or else its possibly binding. Located on the drivers side of the throttle body . Also check for binding aceelerator linkage. One other thing that might sound strange is check the floor mat by the gas pedal. Sometimes gets jammed.
