I have a 02 with the 4.0 engine. I just replaced the iac. I have no check engine light, but when I am going from 25 mph and faster when I shift the idle stays up at like 3000 for a long time . the only way to get it to go down is like put tranny in fifth gear and let out clutch and usually it will drop down. If u wait for it to drop to a lower rpm it takes a long time. So anybody have any ideas at all. I realize that it could b a vacuum leak, but I couldn't find any. One thing that I have been having noticing is my temp gauge barely goes up even after a long trip. Anyone think that could have something to do with high idle.
