I bought this truck two weeks ago, not knowing the amount of problems it really had. My main problem right now is that when you use the throttle you either have to open it up all the way or you can barely touch the it. If you are in the middle of the pedal the truck will rev up and die off. At first I thought it was the map sensor. I replaced that. Now I am looking at the O2 sensor and a Sticky injector. Does anyone have any other suggestions as to what the problem could be.
