How is your fuel system setup? Move the injector in #8 and see if the problem moves with it.


What did the plug look like?

Default Injector

I swapped the injector and it is still the same thing, the plugs look a little white, but all of them are consistant.

#8 is going to see the least cooling airflow, shrouded as it is by
the firewall and the A/C clutter. Plus it's the darkest part of the
engine compartment so will show better. If you look at them all
at night, do they appear more balanced?

Have you used a laser thermo heat gun and looked at the primarys to see what the temps are idling? Ive got 3 that are near 700 degrees idling turns out I have a voltage issue to the injector connectors which I think come strait from the pcm. Anyway off subject but I was just trying to find out how hot they were
