Which port misfire? You sure the coil you replace is the correct one? Is it original?

QUOTE(kparam77 @ Sep 17 2019, 10:06 PM) Some cars will let you know which port misfire during ECU scan. Not sure about yours. In my experience, it might be faulty coil. Did you used the genuine one? What did your foreman said?This post has been edited by h0riz0nLine: Sep 17 2019, 10:14 PM |

Hmm. So the scan turns out fine? No check engine light whatsoever after the repair? How about the time when u sent it in? Did it show any light?

QUOTE(kparam77 @ Sep 18 2019, 12:08 AM) Hmm. Could It have something to do with the wiring? I'm not sure though. Had 1 similar case with Myvi before. It turned out that there was a bad wiring issue. But it was an old car, so I wouldn't bet yours is the same. There are too many probable causes. Fuel pumps etc etc. It would be the best to let your foreman diagnose it. But please do update for the result. |

so is it really misfire? should not vary with speed right?
at neutral, just rev the engine and you should see misfire or not. |
