Vehicle: 1983 280zx N/A, 5 speed, EFI
Pulled engine to completely reseal...was running ok before. Re-installed engine, replaced electrical connectors. Cleaned up itnake manifold some (deleted non-essential components). I have spark, I have fuel, mechanically timing is correct and valves have been adjusted to spec, checked compression (160 psi on all 6 cylinders). Will not start unless distribuor is at full advance but will not idle on own. Revs strong from 1-3k, after that there is terrible hesitation.
Noticed that rotor (inside disributor) was easy to turn to full advance, disassembled and found springs to be worn, replaced and condition did not change. I feel like the dizzy has taken a $h!7 but I am open to any advice. Thanks!
