Was it wet with gas (stinks bad; dries itself off) or oil (stays wet 
forever)?

If the plugs are wet with FUEL, find and fix that ASAP.

If the plug(s) are wet with OIL, OK, then check compression etc.

With badly wet plugs, it won't idle right etc so don't chase multiple 
symptoms, you'll go crazy with the infinite interlinked branching 
possibilities...

Oil or fuel on the plugs?

Did you lay out all six plugs? Are they the same more or less?
