I have a 2002 Jeep Grd Cherokee, in the past 3 yrs it has had surging problems when at speeds above 45 mph. I've had 3 IAC replaced when engine light comes on. I've also had the tranmission rebuilt, it still surges whether it's in cruise control or not. Also noticed when it's warmed up it surges more often. It will surge 200/300 rpms, then back down to rpm speed. It does it more often when in over drive at 55+ speeds. At wits end on what problem is, I've asked several mechanics, no one knows. Please help !
have the same problem?
