This is what my mechanic said when I dropped it off w/ him today. BTW, fully charging the battery did not change anything. He also said he's seen worn distributors act like this, he checked the up/down shaft movement and said mine was borderline and would check it further. He had to replace another one earlier this week and still had it at the shop.

It sounds like an initial enrichment problem, although to my knowledge, this is chiefly controlled by the CHT, and the air temp sensor in the AFM. You might want to check the latter of these if you've already replaced the CHT.
Since this is my thread I get a second guess...I suspect the AFM but I don't have a spare lying around to test that theory, hopefully he does.

Make sure also that the vacuum lines to the fuel pressure regulator and damper are on securely and sealing properly, including where the Y connector attaches to the throttle body.
Did this, several times.

It would be interesting to check fuel pressure and regulator function as well. If you're still coming up empty, you might want to try FR Wilke's mod on your AFM. Search here for posts on it.
I'm aware of it including the testing w/ a 9v battery. Unfortunately, I'm time constrained. The car must be drivable by next Fri. so I gave it to my shop to resolve it.

Keep us posted on what you find out and good luck,

I will update the post with the shop's findings, hopefully it won't be too painful (or embarising).
