Default High idle
2008 ultra. Idleing at 1500 RPM when warm. Tried the switch on switch off 6 times trick but did'nt solve the problem. Also, I'm running FUEL PAK. Problem had been intermittent but now doing it all the time. Any ideas? Maybe dealer reflash?

Dealer had a flash download to fix this a few years back. Can try that. Can also try cleaning the air pressure sensor in the throttle body with a MAF sensor spray or the like.

I got it fixed. I removed the plug going into the throttle body and then I noticed 2wires going into the plug had some copper showing through the insulation. Taped them up, cleaned contacts, used some dielectric grease and now idleing at 1000 RPM.
