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.

it will be on the throtle body this is were the throtle cable hooks up to unless it is a drive by wire (no cable) then it will not have a iac if you are having idling problems with an drive by wire you will need to replace the throtle control $$$$$$$$$$ 500 600 for part but it is a bolt on and go part no programig

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.

Testimonial: "Im relieved to here that someone else is thinking the same thing. Im still going to try it myself as i am somewhat skilled at this but Thanks a bunch!"
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.
