Mark, one thing I forgot about but remembered tonight while posting in a thread on the planet. I know a few members there had an issue with the shear pin on the end of the camshaft breaking off. Not sure if it was 3.2, 3.5 or both. Dont know if that would cause the exact symptoms you were having or not. Its possible that the cam isnt turning and #3 valves are open and #1 are mostly closed. I've heard that these engines can run reasonably well on one bank.
