well heres what I got

I swaped the plug to another cylinder and it was clean in that one, the one in # 6 was getting dirty like carbon or oil?

But I checked the wires and coil packs without pulling the plenum and heres what I have.

1/6 20.6
2/3 21.3
4/7 19.0
5/8 20.2

so I guess its time to check the injectors man this sucks.
