Well I finally got my burning oil issue under control (replaced PCV valve) and now I have another problem. It seems that I am running rich in cylinder four. The spark plug gets fouled within 10 miles of driving. Ive replaced it 3 times and the same thing happens each time. The other three spark plugs look perfect each time I take them out. Why would I run rich in 1 cylinder? My guess is a faulty injector. Im going to take it out today and replace it. Any other suggestions?

 

Nope (no other suggestions), injector is the logical solution.

 

same thing Spade said.

 

you guys are most likely right, but what about the spark being low/ not strong?

 

But then again how can I tell if it is oil on the plug or excess fuel?

 

I hate it when I assume that someone has check the plug wires....I know that he has checked the plugs (i.e. replaced it a few times).

Try a plug wire from a friend and see if there is any difference in the butt dyno.
