Ran compression test on Bank1, pulled fuses 62/64 for coils and held pedal down (flood clear mode so the injectors don't fire).
All the cylinders on Bank1 were between 155-150 psi so pretty balanced, this was on a cold engine so would be higher I'd believe at hot. Since my issues happen at cold I was interested in testing here. Cylinder #3 was @ 154 psi so was towards the top psi wise.
