I replaced my plugs and was because my car was missing very badly it had stock old original spark plug wires. I got Taylors OTVC the kind you have to make (my freind who works at a stereo install place has been doing wires and stuff crimped them all for me)Iinstalled them and routed them. I also got stock A/C delcos didnt gap them just threw them in. Car runs and starts but misfires like crazy dont know whats up?

 

maybe he routed them wrong?

 

they are probably gapped incorrectly, i bought some AC delco plugs and they were gapped at .075, which would cause a misfire, try gapping them to .045 or even .035 if you want more performance.

 

Are you getting any SES codes with this? An engine misfire should throw PO300, just curious did the problem start immediately after the plug/wire change or did it take a couple of miles? I'd definately check to see if he routed the wires correctly, the distributor is like 2, 8, 6, 4 from bottom to top on the passenger side, I can't remember the order on the drivers side, but it's printed on your distrib. anyway.

 

I replaced the wires one at a time to make sure they didnt get crossed I will check the order though. I dont think thats it becuse it sounds fine at idle.

 

Optispark?

 

Wouldnt the car not run at all how does that work with the magical OPTISPARK.

 

The optispark will miss under a heavy load, like during acceleration.
