Don't feel too bad Brian, I spent three weeks this summer diagnosing painfully poor running off-idle. Car would start right up, good throttle response in neutral, pull out of the drive and it wouldn't rev over 2500. My troubleshooting went as far as flow testing injectors, and re-checking cam timing, because replacing a cam seal was the last thing I did before the crappy running. I was moments from calling a flat bed too before I decided to do one more back-trace of everything. The culprit? Wait for it.....a rag I stuffed in the turbo inlet while it was apart for the seal rapair!

You just never know with these old girls and, in my case not yours, their weekend mechanics.

For anyone coming across this mea culpa, the lesson is that the problem isn't always where the symptoms lead you. When the engine would puke, the AFR gauge would show really lean, so I was totally focused on the fueling. Restricted airflow makes it lean? Well sure, when the fuel is metered by a barn door flapper.

Glad to hear you'll be burning it up in that beauty soon.
