So one update my title should read CEL Above 85 mph. I was letting off and not looking at the speed the first few times this happened.
I installed the coils today took it for a run engine performed better smoother idle. CEL still returns around 85 MPH. Checked the codes again still getting P1325 Porsche fault code 901 inlet camshaft bank 2, P0304 Porsche fault code 511 misfire cylinder 4, and P0300 Porsche fault code 507 misfire detection (total).
Still only happens at speed can run to high RPM in fist and second without happening. Trying to decide what to do next.
