miss is driving me crazy

[ndevillo]

1992 Base model. I had a problem where the car just died, found the problem to be the rotor cap screws had backed out. Put it back together with a coil driver and the thing ran awesome. Then a miss started to develop. At first it was only when you took off from a dead stop, thinking it just needed cleaned out, I romped on it, it spit and sputtered and ran like crap and the "service engine soon" came on. Pulled in the driveway, shut it off and it would not start. Found that problem to be the nuetral switch. Changed it out and it started right up (then found out about the service bulletin) and relocated wires (purple 10 guage) best I could. Now the miss is always there and after a few miles, the service engine soon light comes on. I have checked the wires to make there is fire to each cylinder, checked the resistance of the injectors (all were 12.7 or 12.8), removed the injectors plug and engines drops about 50 RPM for each injector removal. Any suggestions??

Sorry for the delay, I was out of the country. When I ground A and G, I get this:

1. H72
4. H26, H28

maybe but when I as having a problem before I changed the coil with a new one but I can try another and see what happens.

[aquaholic]

if you already replaced it i wouldn't do it again. i dont know what those codes are but c4c5 may respond back. have you checked your fuel pressure?

HI there,
What type of ignition wires are you using????
The coil wire may be compromised also.
Start the vehicle up in a dark place or at night and look for arcing.
