Can someone take a stab at this.....maybe PCM related
 

Basically, my drivers side 4 cylinders are not firing. The pipes on that side stay cold and the passengers side pipes are getting hot and firing normally when I run it.

This started happening out of the blue while driving and I haven't done any work or repairs at all.

I checked the harness visually and it looks perfectly fine, I shook it and moved them from the PCM to the coils and it doesn't help. All plugs and connections are good and tight. Fuses are good under the hood.

PCM is 12 years old, maybe its toast.

No SES light, no codes.

weird.
