Well, I did some more poking around and see that the cylinders where the spark plugs sit are filling with oil. Not alot but enough to cover the plug lightly and Id bet that this is part of the issue. Next up, valve cover gaskets and seals and ofcourse fixing that @%$$## plenum.

Guess Ill take all the sensors off of the bad and put on the good just to be sure.

Will keep ya posted.
