After a 180 mile trip over the weekend, I noticed my Trackers idle was hanging, around 1100 to 1300rpm. As of today, Ive tried: Pinching every vacuum hose coming off of the TB and intake, no change. Removed cover for thermal IAC and the wax pellet is firmly pressed out. Removed ICS and tried cleaning it (Wasnt very dirty). No change. I had a timing light hooked up so I can view RPM from engine bay, and backed out idle adjuster screw. To the point it wasn't even touching the throttle shaft anymore. So butterfly fully closed and idle wouldn't come down past 950. (Took photo for reference for where to put screw back). Also sprayed WD40 around TB, 2 times. No changes, the idle wont drop. I've run out of ideas. Anything else I should check or test? Note, Tracker is a manual. Other then the idle, it runs fine. Passes Calif smog. On my trip I was getting 26 mpg. No engine light. Thanks in advance.
