I'm trying to find out exactly which pins on the wiring harness control the coils. I want to check continuity between the coil wires and the ECU. '98 Trans Am.

2 of the misfiring cylinders don't seem to be igniting. I pulled a plug and it looks brand new, minus some raw fuel.

Thanks!

EDIT: Nevermind, thanks.

Have you verified spark being produced by the suspect coils? Did you try swapping the coils and see if the problem follows or stays?

Yep. Swapped coils. Swapped injectors. We verified last night that there is continuity between the PCM and the coils, as well as between the PCM and the o2 sensor that was throwing a code before being replaced.

Have you verified spark though when the problem occurs? And have you done a compression check?

Negative on both. Haven't had enough garage time and it's been ass cold lately as I'm sure you know lol.
