      I have a 2005 Explorer that I am trying to replace the Idle Air Control Valve on, and I can't find where it is on the motor. I have a repair manual and have called and visited numerous parts stores and no one has been able to help. The motor is a 4.0 SOHC, and the valve is supposed to be where the breather attaches to the throttle body, or somewhere close, but the Motorcraft part that I bought to replace the factorypart doesn't seem to exist anywhere on the engine. I have checked to make sure that the part is the correct one, and have found that it is the only one available. Does anyone have an idea of where the part is?
      Thanks,

      Thanks. Why would the engine code definition say that it is a faulty IAC Vavle? What else could it be that would cause an idle problem?

      This appears to be accurate info. My own '04 has no Idle Air Control or Idle Speed Control as it was earlier called. Ford Engineers seem to have decided that the system of driving the throttle plate with a motor ("Drive By Wire") is accurate and sensitive enough to open and close the plate that slight amount necessary to control idle speed as engine load changes due to accessory loading (alternator, A/C, etc.).

      It seems to work! imp
