with a little more research I found this:
The front of the engine is pointed toward the right fender. The firewall side of the engine is the "right" bank or #1. The radiator side is the "left" bank or #2. Also, according to the service manual there is a cam pos. sensor on each bank.
so that would point to my problem being with the left bank
