Okay, so my buddy (He has been building engines for decades) looked at it yesterday. Hooked up one of those super expensive Snapon scanners. The o2's are reading fine, so it seems the o2's and cats are good. He saw that cyl's #5 and #7 were misfiring. At times #8 would hop on the misfire bandwagon, and #6 seemed to be having minor issues as well at times. He swapped out all the driver side coils to some from his LQ4, the problem remained. Injectors seem fine.

At this point he thinks it's either the ECU or wiring in the harness, possibly even a bad ground somewhere. Some random electrical issues pop up such as the turn signals blinking real fast, then real slow, then fast and slow when I activate them. Also my third brake light will light up like a regular tail light: On while the parking lights are on, then when I hit the brake it gets brighter. When revving the Check Gauges light 1/4 illuminates sometimes, which is odd. A few other odd things occur from time to time as well.

At this point I need to find a '98 Camaro SS or Trans Am computer and swap that in there. See if the problem is resolved. Anyone have one to loan out?
