    i almost forgot about this issue i had. when my truck is cold it does'nt want go when you start out, it idles good, but when you start to go it stumbles as if the choke was'nt working ( i know there is no choke ), but i did have to repair that piece in the air cleaner the one that operated the cold air flap, was wondering if that might be a problem, or THE problem?
    can't think of anything else that would cause that

    I have read that the temp sensors on these can cause problems.

    EGR valve? Maybe the aftermarket intake?
