The best log would be a cold start, warmup to closed loop (about 3 to 4 minutes), and a drive of several minutes, including low load and WOT, and at whatever conditions replicate the problem (if it happens under load), followed by a 15 second idle period before you shut it off.

 

Well, I was totally off with this one.

Reset the valves today on the drivers side, and the car runs fine now.

I did have a slight tap, like a hung up lifter, however when I pulled the valve cover off, one of the rockers loosened to the point the push rod was not even attached.

What the hell would have caused that?
