1998 Chevy Venture, 130,000 miles, enging had problems starting would crank and have a hard time turning over. When it did turn over and you gave it gas it would backfire under the hood and sputter, but would start. Changed fuel filter, plugs, wires, air filter, TPS, still having problem. Oh also should mention slight hesitation when taking off from a full stop jumps a few times unless you push VERY lightly on accelerator. Anyway since problem did not stop changed throttle body and coil pack and right after there was no more hesitation but I woke up the day after we changed those things and the van will not start at all now, it trys to turn over but then I just get a hum that fades out. Won't start at all. The fuel filter does come on I can hear it. The coil pack and throttle body were from a junk yard off a Venture that started right up. What do you think it could be? Also when it did run it would slightly accelerate on its own even after changing the TPS. HELP
have the same problem?
