I believe there is a software update for similar issues. Check out Technical Service Bulletin TSB 18-018-06. This TSB says to flash/update the software on the powertrain control module (pcm). The dealer may have done the update? They should have done the update when they changed the throttle body and harness. Possible causes are software updates, pcm(computor), throttle body, or harness.
