Gave it some revs after oil temp was up then it gained a new feature.

Idle went to 1500 with intermittent slow rev up to 2500 and then back to 1500 non stop all on its own.

Either tune is gone or someone suggested throttle bodies need a relearn.

I went around the block quickly tube seems ok had fuel with no bogs or gasps so think tube may be ok?

Wtf.
