WONT REV OVER 2200 RPM
Posted to HD/Fleet Forum on 9/17/2019 4 Replies

this vehicle has no mil's on in dash and no obd-2 codes stored. it seems to have plenty of power and all fluids/ visual inspection is okay. the concern is that the engine wont rev over approximately 2000 rpms. when driving on flat city roads this ends up being hardly noticeable but when trying to go up a hill, it hardly will go. cleaned throttle body as it was fairly dirty but no change at this time.
