Alright so I increased the idle, timed it to 10 degrees, then brought the idle back down to 800.  It’s running so rich now that it burns your eyes when you stand behind it.

this makes no sense at this point.

any ideas?

Check all of the connections in the vicinity of the distributor.  Check the hoses too.  Check the FPR vacuum hose for fuel.  Watch the tachometer needle to see if it's behaving normally.  It shows you what the spark is doing.

Might be that parts on the engine are just starting to fail.  You fixed one and just need to keep fixing.

Coincidentally I cleaned the bullet connectors & afm connector a week before the car died and it ran better than it ever had.  I also smoked the engine last week and no leaks could be found.

Just checked the fpr and no leak.

tach needle is perfect too.  This is so strange...

EDIT: the coolant temperature sensor connector bullet connector popped out.  Thanks for the tip.
