I r&r Intakes IMRC controls and replaced one actuator. Upon engine start up idle will not come down and continues to rise. I disconnected IAC but speed did not drop. IAC opening in throttle body draws alot of air, if I shut it down with rag engine will slow down. Is this the only item that could cause this extremely high idle?
