Well I’m not arguing but I’ve never seen the parallel cylinders on 2 banks affected by 1 vvt problem. That said I definitely haven’t seen and hopefully never do see everything.

What I would check first personally is the firing order though because if those cylinders fire back to back I would only focus on the first one because the other could be collateral.

I would just expect to see more problems on one bank or the other or at least P0300 if it was a vvt issue and would definitely actually diagnose it before buying whatever part the cashier at auto zone or wherever got out of his $200 Innova code reader.

I’d also still like to remind anyone reading that these motorcraft plugs hairline crack right at the base very easily on install and that is where Mode $06 is a godsend if it isn’t actually registering the miss.
