Reply to "UPDATED - Backfire under Low RPM / Load (4th or 5th Gear)....."

rockyMember

I pulled the plugs, to see what I can see...

It looks to me that I may be running slightly rich all the way around, but the rear 4 cylinders are much richer than the front four....

I think maybe I could go 1 plug hotter, too.

I can get better pictures, with the plugs reoriented, but even if this isn't my backfire issue, it's something I want to look at.

Would this be more of a WOT situation, or not? I understood the primaries are supposed to feed all 8 cylinders equally.

Thanks -

Rocky
