new taylor ovc's, new ngk tr-55 plugs, new coil, new coil wire, and heat sleeving on all the wires and i am still getting a ridiculous misfire that causes my SES light to blink and when the car is sitting idle u can hear the banging....what am i doing wrong or wut else is there to check other than just assume that my optispark is bad??

 

are you 100% the wires are on in the correct firing order

 

yeah all the wires are in the correct firing order....so im left clueless as to what my problem could be...unless its the opti...

 

Are you sure it is ignition related and not something involving something fuel related like a clogged/dirty injector.

 

Agreed. Test fuel pressure at the rail before condeming the opti. If that has good pressure there are a number of other tests you can do to determine the problem.

 

ok thanks for the help guys but i definitely found the problem myself earlier...i decided to check all the wires and plugs again to make sure the plugs were in correctly and the wires were connected to the plugs correctly and i also have a tool that connects one end to the plug and one end to the wire and it lights up if u are getting a good connection...earlier i had felt the misfire from the drivers side cylinder #7 and had figured that the wire may not have been connected right but it was and upon inspection of it...i noticed that about one inch up from the 90* boot that connects to the plug, the wire had been burned almost completely thru...probably done prior to my installation of fire sleeving...so i have a new wire on the way and fire sleeving for it b4 it gets to that point again...thanks for all the help tho...stupid mistake on my part...
