Also, make sure there aren’t any fuel pressure problems. It might be worth checking the fuel pressure sensor or mass airflow sensor as well. Without that, the issue might not get resolved. Good luck getting this fixed!

Since you're still having problems with just one spark plug and coil, it could really be an issue with the timing, not the plugs or coils. Also, take a look at oil pressure because if the VVT sensors don’t get enough pressure, things go haywire. Try changing the oil to something better, might help!
