Quoted From EricTheCarGuy:
I’ve never had any luck cleaning IAC’s. Since it happened after you cleaned the throttle body you might want to go back and check your work as something could have been left loose or you may have damaged or moved a connector. Lastly I’m with those that recommend resetting the computer as it might help. Disconnect the negative battery cable and touch it to the positive for a few seconds to reset the system. Good luck.
Hi Eric,
doest it can be done in all car? Is there any problem? Since we short the negative to positive?
