Got one of those vehicles that cause rapid hair removal (pulling your hair out). 3.0 dohc. codes for misfire on first startup and #6 misfire. Power balance graph you can see a misfire on #6. Replaced coil and plug, no change. Replaced injector on #6, no change. You can see the spark duration on each cylinder with the IDS.#6 definately has a problem. I swapped coils and plugs with #5 with no change. Ran injector driver test and coil driver test, all check good. Hotline suggested replacing injectors in #4 and #5 because of the possibility of the two being bad and the 02 sensor detecting it on that bank, causing the pcm to adjust fuel creating a misfire on the only cylinder without a problem.............. SO YOU WANT TO BE A TECH, HUH?

So did new injectors on 4 & 5 fix it?

I certainly won't pretend I'd have figured that out myself, but I can at least see the logic (kinda) by which it makes some sense.
