Hello all I’m trying to pinpoint a problem with my z31. At idle or low rpms I will randomly have an intermittent misfire. Sometimes it just pops while other times it sounds like it’s running on 5 cylinders. I have replaced the maf sensor, chts, cap, rotor, cas, plug wires, looked decent so I did not change them just yet. I’m probably missing more stuff that I’ve replaced. I’ve fixed all vacuum leaks. Not sure if this is relevant but my ecu did stop sending a fuel signal to my fuel pump so I had to manually ground the pump out but I never had any issues with it after that. I attached a video of the issue.
