Does anybody have any suggestions as to why a Ford F150 4.2L V6 5spd lacks power when passing without having to downshift? This occurs all the time. It doesn't bog down but it certainly doesn't speed up. A recent tuneup and manifold gasket replacement has been done. The truck runs fine except for this one very annoying problem. I'm hoping for some help understanding the problem before I have to take it in for professional help.

Because it's a 5speed. It's not like a auto that will downshift when you give it the gas.

No need to open a new thread with the same question.
