As the title says I have a JKU (3.8) that has had some weird idling issues, it occasionally gets stuck at around 2k rpm and then drops again to idle when I am in neutral (6 speed manual). Anyone else have this issue? I have had idling issues with my old tj, but it ened up just being a loose vacuum line. I have read that it could be the tps (throttle position sensor) or IAC (idle air controller). Many have suggested cleaning the throttle body and IAC and that this helps, has anyone done this with sucsess?. Thanks in advance.
