The car will start but when started will shoot up to 2000 rpms and the drop down to where it wants to shut off but does not. Check engine light is not on and no codes are being thrown. Car with about 130,000kms spark plugs/wires and oil changed recently. Throttle body and IAC was cleaned via the throttle body where the hole is. I have read that it is the IAC that needs to be completely replaced but any other further inputs? I would greatly appreciate any help/suggestions. Thank you!

 

Year of car and engine model?
