2007 Freightliner w/Cat C7 rpm control is always on
Hey guys so i got a 2007 freightliner with a cat c7 engine and recently its been doing this thing. i first noticed it when i shifted from drive to neutral and the rpms suddenly bumped all the way up, at a consistent pace. so i pressed the decrease rpm button on the cruise control and it went down. but my rpm control button is off. anyone have any ideas?
