Make sure they are all routed to the correct plug and spot on the opti, no cuts or tears either. Start the car at night and look at all your plugs and wires and see if you can see them arcing. It will look like little sparks coming from the wire.
(to the poster) first off i would verify that you have the firing order correct. it is VERY easy to cross up wires on an LT1 due to the fact you cant really see the wires to the plugs, you kind of have to feel. going with the others, i would check coil next, icm usually is a last resort check for me. i have usually narrowed the misfires to the coil, opti, or burned wires.
