i own a 91 351... ive replaced just about every tune up part you can think of. actually, ive replaced every part you can think of. when coming from a dead stop and accelerating theres a dip in the motion before my truck starts picking up good. itll start off the line ok but then it seems to make a dip in the power before picking up again. also i tested my TPS sensor and the idle voltage is fine but at WOT it only reads at 3.5 about, instead of the 4-5 its supposed to be, and when i try flooring it the thing just accelerates in that gear more instead of taking off. any idea how to fix the WOT TPS problem, and what the hesitation i guess might be
