My Raider is still idling at around 1800rpms. I've replaced the Throttle Body and that didn't do anything. The IAC has been replaced, and the ICM as well. All vacuum lines have been replaced and I also check out the EGR Tube, seems to be good. I'm going to replace the thermostat and the water temp sending unit to see if that does it.

Is there anything else you guys think might be causing the high idle?

Also, I ran it in idle for 5 minutes then turn it off for 10 seconds and started it for another 5 minutes...did this about 3 or 4 times and thought I was making progress but then all of a sudden I'm back to 1800 RPMS....had it down to 1150.

Please help!
