OK, I'll start with the easy stuff. Vacuum lines are new (less than 50 miles on them) and gone over all the diagrams to get them correct. Even had the car at a Porsche repair shop to get it to run better. Decel valve at idle pulls very little to no air. More revs, I can feel suction. AAR pulls air at idle, from putting my finger over the hose end. But that causes the engine to slow and die. Haven't tried it with a warm engine yet.
Timming - more difficult. A few years back I put these two white marks on the fan. Don't recall why other than so many degrees BTDC. The photo shows, kind of how they are oriented with trimming light at idle. I would think, the shop double checked timming when they worked on it but still suspect.
Did this add any clues? Thanks for the response.
