The only thing that made me uncomfortable today was that when I throttle back to stay out of the red arc on the A/S to about 15 manifold pressue, the engine goes into the unstable up and down hunting that no mixture ratio seems to fix. Any ideas??
Bernie, 13+ hours now.
I would guess that you have a portion of your mixture map "corrupted" or mis-programmed. Just a hunch.. either that or (not knowing a single thing about your upper deck setup) perhaps your MAP sense lines are in a turbulent spot behind the throttle plate(s). Just thinking out loud without any practical experience to back it up.
