LLY: Which injector is bad?

[hopkins_fam]

Ok even though all my balance rates are good and truck doesn't smoke i think i have a bad injector that is causing my lope on top of a horrible injector knock.

Since nothing electrical is telling me i have a bad injector can the spray patterns on top of the piston be a clue to a bad injector?

When i done HG's all the patterns looked awesome except for the rear most passenger side.

That rear piston looks cleaner. Less soot I would think because more fuel. I bet that would be your bad injector.

That's what Im thinking as well. Almost all the others touch can see a perfect spray pattern from the nozzle. All except for rear passenger.

Also when viewing the injectors on something like a Snap-On Solus is #1 injector on the Solus the #1 in the firing order?

All my balance rates are within +/- 1.0 after she's warm, I've changed FICM and got a good harness to try also. When viewing on the Solus though there is 2 injectors that are commanding a different PW than the other

#1 is cylinder #1. #7 is cylinder 7.
