SOURCE: IAC control valve. Locato\ion 2002 ford escape

If it's not idling and has problems starting, it's probably the IAC motor. It's located on the throttle body. Follow the airfilter box all the way to the engine, where the rubber flex hose attaches. The throttle body should be the first aluminum part you come to. Attached to the side you'll find small little aluminum part with a small wire harness attached. Unplug it, take the IAC motor off and clean inside with carb cleaner. This should fix the problem with the idle.

SOURCE: Need a pic veiw of 2004 ford f350 6.0L diesel EGR

1st of all when Ford started out with putting "EGR's" on those diesel engines, they rushed it and are nothing less than a pain in the ***! i recommend having an EGR cleaning service performed by your local Ford dealer, i know they charge up the wazoo, but they're the best people to perform the service period.this is a VERY common problem with those engines and that service is "supposed" to be performed every 30K I believe. i dont recommend attempting to remove and service it youself, this WILL only make it worse.

SOURCE: location of iac valve f150 5.4 triton

This particular vehicle does not have an IAC valve. This is because it is equipped with ETC (Electronic Throttle Control). This means there is no mechanical connection between the accelerator pedal and the throttle plate. Instead, the throttle plate is controlled by an electric motor to control its engine speed, based on "input" it receives from the PCM. The accelerator pedal is connected to three poteniometers. Two that increase, and one that decreases voltage in a particular proportion. If they fail, the vehicle goes into what's called a "forced idle" mode of operation. Hope this helps.

I need to know were the IAC valve is

For a new Body style 2004 ( not a Heritage or Lightning ) there is not an IAC.

The IAC functions are now part of the throttle by wire operation in the 2004-08 MY F-150s.
The Throttle Plate Position Controller is part opened by the PCM ( actually a chip embedded in the PCM specific to this function ) when the engine is at idle and the throttle is off ( i.e. not be pressed down ).

If you are talking about a 2004 Heritage or Lightning ( the same body style as the 99-03 MY ), the IAC is on the back of the throttle body, under the plastic throttle body cover.


Not too sure which 2004 version you are talking about, just wanted to cover both 2004 options for the location on the IAC.

  3. Remove the Idle Air Control (IAC) valve electrical connector.
  4. Disconnect the throttle bypass hose.
  5. Remove the mounting bolts and the IAC valve.

Iac valve

it is located on the top of the engine, mounted either on the side or top of the throttle body (close to where the throttle cable hooks up) should have a small connector on it with 2 or 3 wires

Idle air bypass vaule

The Idle air control valve (IAC) is on the back of the throttle body housing on the 4.6 V8, it's half the size of a can of Red Bull. Try tapping on it with a small hammer and if the truck clears up then it's time to replace the IAC.
You can clean it with Throttle body injector but that's just a quick fix for now. Good luck and hope this helps.
