Gen 1 Coyote. Used to idle at ~ 1800 rpms for 7-10 secs before dropping to a normal 800. Does the same when stopped at a light. Have been working with a tune outfit to log rides and the flash corrective tunes. It has helped some, but it feels like the car wants to re-learn the high idle.

I've checked for vacuum leaks (with both propane and starter fluid); no leaks. Cleaned the MAF sensor.

I recall that with my MKII, the TPS voltage effected the idle. It's the last thing I know to do, so how do I go about this on the Coyote? What is the target voltage? Is there a Youtube video out there?

Any other thoughts?

Oh, Speed Dial is installed.
