Have you checked the condition of the Opti harness connectors, on both ends (gray connector on the side of the intake manifold, and the connector that pushes into the Opti)?

Yes its one of those Dynaspark ones with the wireing harness built in to it. Its just really weird going through all these it has to be something shorting out these sensors or something. my coil is arching on the sides and my icm is old as heck could any of those be causing this to happen i can also see some of my plugwires arching on the ovc style with taylor wires

I've never had any luck with any other opti brand that ac delco. I use stock opti's with MSD cap and rotors.

To answer your question the coil may not be helping your power. I'm still running my stock icm and i have 170k on my car.

If you've got high voltage arcing at the distributor, its possible the voltage is discharging near the harness wires for the optical module, and overloading the module.

Yea it seems the opti is just going out when the car drives about 10miles then it will just shut off and i can start it till about 3 hours
