I had been having idle issues. While driving on the highway it would randomly buck as if fuel cuts off then back on then go back to normal. It would randomly idle strange and shut off at lights and that seemed to have been fixed after i replaced the IAC. I also got around to fixing my check engine light and finally got it to work. It was off but i was able to pull 2 codes from it. Mark came by and scanned my jeep and he said that my TPS was bad so I replaced it and the IAC at the same time.
Code 35 Cooling fan relay. Check relay and circuit.
Code 36 Air switch solenoid circuit. Air switch solenoid circuit (non-turbo) or the waste gate solenoid on turbocharged models
I drove it to work a few days after replacing the IAC and it did great. I then drove it to big bear, wheeled it and drove home with 0 issues. Yesterday I was on the hwy and I went to pass another vehicle and as soon as my xj downshifted the check engine light turned on and it went back to having the same problems. I get to my destination, turn it off and back on and the check engine light is still there. I go to drive home maybe 20 mins later and its still acting up. I stop at a gas station and when i drove home the light was off and it drove great.
