Komatsu FG25T-16:
Fast Idle

2006 FG25T-16 dual fuel but on gasoline. Was running OK just excessive cranks before it would start. I cleaned the throttle body with engine tune now the idle wont come down. It seems to be stuck in cold start mode. No vacuum leaks, nothing misrouted or unhooked, all I did was clean it. I tried new o2 but did not change. No check engine light. Tried adjusting sensor at gas pedal and the set screw at throttle body with no help. Did I smoke a sensor?
