Im guessing it could be the IAC Valve ( Idle air control valve ) , should be a post under the Maintenance Guides to show you how to clean it .

I would clean above mentioned valve and the throttle body first if you have no codes stored

Unplug electrics, remove hose at front & pull ICV away from plenum.  Clean with carb cleaner (squirt & shake) - do NOT try to open valve with a screwdriver etc. - when clean lightly oil (3 in 1) and refit.

Note it may take a couple of goes to fully clean.
