that truck has the spider injectors. they are known to break but dont think that is the problem here. i would go with the MAP sensor first. make sure the vacuum line is on it and in good shape before you go buy one. if MAP dont work then the O2s are cheaper than the MAF and on that truck i think if the MAF is bad you wouldnt be able to drive it very good at all(unless its stuck all the way open). it would backfire and not get enough rpms to get you very far. another thing it could be is the EGR or fuel pressure regulator.

Good Luck
Bud.
