Hey looking for advise for a problem with my gas 93 cheyenne 4x4 I've just been putting off for the last while. In the mornings or after work when the truck has sit for a few hours it starts and idles fine but if you put the pedal down fast it hesitates and chokes and doesn't want to speed up. After the engine gets up to operational temp or after you get past that initial struggle it runs fine all day pedal to the floor and all. Fuel pump or vacuum leak or what do guys think?
