Default Misfireing hardcore spontaneously....

Alright guys, im bringing this back up, no one really answered me last time, i though i fixed it but its back, heres the deal. Got my car running, obd1 90 crx dx with a d16y8 motor, using d16z6 im with map, p28 ecu, 450's, vafc2, 9psi on an rhb5, etc.....

Got it running with the z6 dizzy i was suing before, worked fine, but had to mount it so it was reallllllllllllllly retarded, ran, but would hesitate HARDCORE, as in, if i leave my foot on the pedel when it started to do it, at the same spot, the motor would gradually stop firing, and be silent, until i floored it or let off the gas,..... weird....

Swapped to teh y8 dizzy, set timing at a more respectable retard, around -8-10 degrees retarded, and it ran fine all of a sudden, GREAT!,,,, two days later its doing hte same damn, thing, i tried advanceing the timing more, but didnt help, i tried leaning out my settings between -45% and - 38% on narrow throttle, and when i lean them out to -45%, it gets worse. Itr will run shitty when i start it up, then a few moments later run fine, then after driving for about 10 minutes, it runs like ---- again, then it will run fine a few minutes after that. I dont know whats going on. Spark plugs where gapped to about .030 or maybe even less, and the other night trying ot drive it when i was being ghey, it threw a code 43, for feul system, and then ran fine..... well, rally rich, but it cruised.....

My tps voltage readings on teh vafc were

.40-45, fluctuated, at closed throttle

and 4.4 at open throttle. Is this far off, or are these decent readings...
