    Heres the issue:

    Idle & Starting off the truck sputters & stalls. every now and then aroun 1500 rpm it will make one small spudder.
    No Check engine light for codes.

    I just replaced the iac today, ran it up the street to lesco and back, seemed fine, but spudder & stalls when in low rpms but allot less.

    Any ideas?

    It sounds like it has a miss. Have you done plugs yet? If not, you're due anyway. A bad coil is also possible, but I'd start with plugs, then hunt down the weak coil. Make sure you use OE plugs, the Ford mod motors are very sensitive to plugs, and the wrong kind can cause issues.

    my 03 f250 with the 5.4 did that, they had to change/clean the idle contoller and it was fine.

    Might look at the coil on plugs. With the gold coolant it will leave a residual that looks like salt spray. I have read that some engines have leakage problems right above one to the plugs. Also some people have had problems with the connection on the coil on plugs. Repair manuals have check out procedures on emissions stuff. Most times that ends up being the problem.
