355 No Power, Shakes. I'm posting this for my brother. He has a 1995 M6 355 w/ 503 cam.
Problem: Car is down on HP and engine shakes in 5th and 6th gear.
New parts:
Opti
Wires
Plugs
ICM
Anyone have any ideas or suggestions?

Thats what's making it so hard to fix. Code tester isn't connecting to the PCM. Will check the fuel pressure once we get a fuel pressure tester handy.

FOUND THE PROBLEM!
Cylinder # 8 spark plug was covered in oil.
What could cause this?
Piston Rings?
Valve seals?
His car has a new felpro intake mani gasket.
