Air leak. Check Fast Idle Valve under throttle body.

With engine full-warm and running, remove air pipe from cleaner to throttle
body. Immediately in front of the throttle plate, there are two ports in
the throttle body. Is there suction at the LOWER port in the throttle body?
If so, Fast Idle Valve is stuck.
