My acceleration fails while in motion especially when I drive over bumps, potholes or when the general temperature is high but the car temperature is normal. I have replaced complete pedal sensor, nozzles, relays, complete fuel pump and housing, crankshaft sensor and top sensor, injector mount yet the problem persists, whenever it happens if I restart the car, it will accelerate and then stops after some time or a day or two. Thanks

This sounds like a connection issue. If that is correct then more then likely we will have some circuit codes that will point us in the right direction.

I am thinking a connection issue that is affecting the throttle position sensor but this is clearly just a guess until we have more to go on.

Let me know if there are codes and we can go from there. Thanks
