exactly same thing happened to my crv and was fixed by my mechanic. i hope you kept the servo, ecu & other parts na pinalitan. montik na din ako dati. what my mechanic did is that he performed major tuneup (PROPERLY cleaned the servo & throttle as well PROPERLY adjust tappet, idling, & timing). ayun naayos idling and nawala yung mabaho na buga tambutso. buti na lang hindi ako bumili ng servo. pm me na lang po if you want i can recommend him to you. home service sya for caloocan, manila and QC.
