so i took my entire wire harness out again and stripped it all to figure out my ignition problem and im stumped. . i can see the problem, i believe but i dont know how to 'fix' it. . this will hopefully be my last question to everyone. i appreciate any help offered. . this is what the car does: if i cruise at a steady speed the car missed on a cylander for a split second then run on all 6 another second. .(it wants to come alive but then its like trying to pull an elephant behind me). i asked in one of my previous posts if anyone knew the ignition harness well? my issue at first was that #1 coil pack was frying. i traced the wires to c if they were grounding out anywhere. i didnt find any..

pretty much i need to know if there is a wire that ties in to the #1 ignition signal wire at all from that second plug(its a 3 wire plug)?? ill try and post some pics to show wut im talking about.

but i traced all 3 wires back from that second big plug the conects the ignition harness, and one is the big white wire that goes to the relay. And the two black ones are all grounds? where do they wire into??? i have a j30 ignitor so its making things confusing, and i cant find a diagram to duplicate another harness...

also, is it true if your 02 sensor goes out, it can also cause you to miss on #1???

help me ...

thank you. . it is but you know that 3 pin plug for the ignition harness? one of the wires ties in to the #1 coil pack signal wire. i even checked on a buddies car. but both black wires on that plug are grounds? and of course you have the big white one that goes to the relay under the dash. . im seeking help to know where the 2 black wires on the 3 pin plug go. thats where i think my problem is...
