Default Firing problem

I'm still having a misfire problem and I would like to know what could cause one cylinder to constantly foul the plug and begin to miss. I have already replaced the plug, wire, and coil pack on #8. Still missing, though it took many miles of driving before the miss reappeared after the coil swap. The only code ever triggered was a lean bank 2, but I know my problem is specific to #8. Can an injector flow too much fuel and cause this fouling? It seems that this problem is triggered after a lot of low speed cruising. At wot the problem is not really noticeable.

Swap the stuff to a different cylinder and see if it follows (injector and coil). You might have a bent pushrod or something.

You probably have a bad injector, as said, try swaping with another cycl. and see if the problem moves with the part... if it does BINGO... hopefully you don't have a mechanical problem..
