My sons 2002 wrangler with the 4.0 engine revs high upon start and stays high for a few seconds. This just started. No check engine light or any warnings.
Cant seem to find out why any ideas

Re: high RPM at start

Start cheap....I'd do a throttle body cleaning and see if that does you any good. The Idle air control motor could be gummed up. They are easy to replace if need be.
