Probably the IAC Valve attached to the Throttle body. Intake Air Control valve. It controls the IDLE and when it gets dirty it doesn't adjust correctly. Do a search here/there's lots of info.

the CEL will generate a code- which any parts store will pull for you for free (except Ca.)
that will point us in a direction
but codes are clues- not diagnosis in themself!
you cleaned the engine--external-pressure wash rinse? spray can Gunk and gentle rinse?
or internal- seafoam or bg or similar fuel product?
external= I would ck all connections to coils and all exposed electric connectors-
wd40 is the tool for this job
wd actually means Water Dispersant, Test Formule #40 = WD-40!!
