Misfire

My vehicle has 200hp manual full straight pipe exhaust. I changed the top cover valves to my vehicle. After it is loaded into the gas constantly after the white smoke problem. I changed the coils, we still couldn't solve the reason, but when I say thp misfire, everyone says high pressure pump and vanas. Arda Dinçer 2020-01-02 23:35:07

I heard it for the first time because of your fault, but are you cracking up in the engine or somewhere else? Whether you have an arc jump to the motor shaft, you need to check it thoroughly.
