So much for getting that done last weekend.

Compression comes in between 135 -140 psi with most right smack in the middle at about 138. I need to verify my methodology, I had all spark plugs out and for each test cranked 5 revolutions. I also checked it with 7 revolutions and all come in just a hair over 150 psi. Let me know if I am off base and should be taking the first or second reading.

New Bosch spark plug wires have made no difference.
