Q: High idling on a 1998 Cadillac Deville

asked by on June 08, 2016

I've got a 1998 Cadillac Deville. The car runs well but randomly the outer shoots are way up and get stuck at 2400 RPM. I cleaned the throttle body, checked the throttle cabel, disconnected cruise, replaced IAC and TPS. Just can't fugure it out.
