Using the Torque app, I can see the cylinders #2 and #4 are misfiring. I tried the following:
- swapped 3/6 coil with 2/5 and swapped another used coil with 1/4, no change
- Swapped #2 and #4 plug wires with new. No change. Triple checked to make sure they are routed to the correct cylinder.
- Pulled #4 spark plug. Looks good. Gap under 0.060". Replaced anyway with new plug gapped at 0.050". No change.
- Motor oil looks good. Coolant looks good and full. Engine did not overheat that I know off.
