    Your truck has a two piece intake manifold. You will need to pull off the plastic upper half, and you'll find it attached to the fuel injection manifold.

    Oh man! lol Im pretty good with working on cars but never did anything with the manifold or anything and really am not sure what it is lol I think its where the intake is mounted on? like wgat would be the carb in an old truck? So do I have to remove all that to get at it? Is it hard? Anyone have a pic? lol sorry about all the questions.
