* MB DOC, thanks for your input.
* Yes, do have live data (via PC Retriever). Reran live data this morning and have misfires on cyls 1-4 (not just 2, 3, and 4). So you're right that it's a right bank issue. Did have a couple of misfire blips on the left bank during a brief warm up period but no left bank misfire after a brief (not full) warm up.
* Did a compression test yesterday. With cold engine, cranked to highest reading. All eight cyls 185-200 psi. That falls at the upper end of 10-14 bar w/ a warm engine.
* Car ran without this miss when it came in. Just the ticking noise. Could a cat turn bad that fast? Thought that the plugged cat signs were more gradual. If I mistimed the cams, which I doubt that I did, could this cause right bank misfire codes? The timing pins and the 45deg BTDC starting point make that pretty straight forward. That's why I was wondering about the wiring.
