To diagnose a misfire, I would check spark, fuel and compression on all cylinders.

Sometimes after a lot of work on the car the fuel has gone bad from sitting. This sounds like the job that I want to do.
Or - as is usually the case with me - it is something that was overlooked.
Good luck, great car.

Running to lean - open up the AFM and click up the mixture 5 notches - be sure to silicone seal when replacing the cover.
