No bites on my car sale, so de-modded the car. Removed Roush Supercharger, and now getting a heavy misfire.
Code and live data indicate Cyl #5.

Put different set of plugs in, same result.
Switched coil packs between 5 and 6, same result.

Stock injectors sat for 5 years. Only 7K orig miles on them, not sure if they could go bad just sitting around
(can ethanol fuel kill them??). I mean the rail was empty when stored, so don't think it was long term fuel damage
(but who knows).

Anyway, I...
