I have a 1998 Wrangler TJ (manual transmission) and I have and idle around 3,000 to 3,500 rpm. I have replaced the TPS and the IAC as well as distributor, crankshaft sensor, and ignition coil. I still cannot get it to idle down and when I touch the gas pedal the idle then stays at the rpm that it is on when I release the pedal. I cannot figure out why. It doesn't seem that the throttle cable is stuck nor that the vacuum hoses are bad or clogged. Any Ideas??
