94 camaro Electrical demons - Ignition

I'm having issues with my 94Z shutting off intermittently. Ive read the codes and its showing a loss of low res pulse signal. Having already replaced the Opti, the Opti harness, and the PCM, i'm left at a loss as to why this is happening. Anyone Help?

Re: 94 camaro Electrical demons - Ignition

I appreciate the links and have investigated those options. Since i've already replaced the opti with an accel unit, replaced and re-programmed the PCM, and replaced the opti harness, the last link is in the Master engine harness. Any Ideas?

Re: 94 camaro Electrical demons - Ignition

With what you did, I would suspect the Accel unit, first. Many people have had less than stellar results with it. The AC-Delco/Delphi/GM opti has about the best track record out there.
