Engine light comes on...
Ok. I've got a 2010 ultra with 18k. As I was pulling away from work, my engine light came on and I lost throttle power. I stopped, turned it off, started it again, and let it warm up, then went off again. Went fine for a few miles, then did it again. Repeat. Started backfiring and lost throttle power. Repeat. Started back up and kept RPMs under 3 and seemed ok. Just did a 15k service on it. Any thoughts what could be going on?

Suspect connection on back of throttle housing bad connection. Common problem & HD has a Tech. Bulletin on this very subject. As stated above check codes. DTC codes P0120, P0122, P0123, P0220, P0222, P0223will indicate this.
