I have a 1996 F-350 powerstroke with only a TS Performance chip and exhaust my question is the truck idles fine and starts right up on cold mornings but when im driving and i go to accelerate hard it starts to kinda of sputter then it picks up but if the motor dont have much heat in it it wont do it. I thought maybe it was the chip took it completely out still does it i ran a injector test all injectors are good and have good fuel pressure. also changed cam position sensor still does it. the only they i can think of is the oil has air pockets in it once it warms up. i would like any input you got. thanks
