If it is backfiring then you have a timing problem. You replaced all engine sensors and could you please explain what prompted you to do so? CPS, (possibly CAM if distributorless) TPS, CTS, KS, MAP, ITS, MAF, IAS. Are just to name a few. Do you recieve any engine codes?

I put a new 5.7 motor in and the new motor is doing the same as the old. New cam sensor, crank sensor, new throttle position, new mas air flow. The timeing isn't off. No engin codes I put in almost all new sensors cuz I had the motor out and it was convenint.
