    Its kind of young but you might want to look into giving your throttle body and plenum a cleaning, seems way to young to have a fouled injector, last time you switched your air filter?

    i just bought the truck a few days ago.. its got 113,000 miles on it.. i will check the filter tomomorow. i was thinking a fuel injector as well or maybe a spark plug..

    oh shite,,,,,with that many miles on it,,,then it may be a bunch of different things,,,,in addition to what i mentioned it may be an injector,,,,a fuel filter, or even a throttle position sensor

    Yes a code reader would tell you alot about the problems. Run down to autozone have them read the codes

    Also seen fuel pumps give a similar condition when they have got weak.
    But if the pump is weak you will normaly also see a lack of performance in another
    area.

    It's your idle air control valve ( IAC ) if it has one. It's responding too slow. Does it not idle sometimes when you start it in the morning?

    That new of a truck your out of luck. That's one of the parts FORD likes to make little changes on. So you have to get it from them for 5 - 6 years. I had the same problem with my Woundstar. I called and looked on the net all day, no luck!
    It was $120 out the door. Normally $55-65 at Advance.

    well i called ford and they told me you cant get it seprate and its showing up on there computer as part as the throttle body manifold. You have to buy the whole assembly. Saying the idle control valve is rivited to the side of it. 180bucks for the whole thing.. iam gonna try running fuel injector cleaner through it the next 4-5 tanks and see if that dont clean it up..
