I own a 2003 ford expedition 4.6 2wd the idle surges up and down and is idleing high. Replaced the idle air control unit and maf sensor and have taken off the throttle body and cleaned it. I have disconnected the idle air control unit and it runs fine. I dont know where to go from here any suggestions !
have the same problem?
