Does it always hesitate and sputter? Every time? Does it hesitate and sputter when its cold engine or hot engine?
Do you have a Check Engine Light on?
Have you ever had the fuel pressure checked?
Does it have shifting problems? Jerking or bucking as you accelerate?
Does it ever just shut off on you?
