Engine Performance problem
2000 Ford Expedition V8 Two Wheel Drive Automatic
My check engine light has come on, and the computer thingie said that the spark plug 6 is misfiring. Unfortunately, the way the spark plugs are located on the engine, it is going to be very difficult to change all of them (which was my first thought).
So my question is, how can I make sure which one is the number 6 spark plug? I have a Haynes manuel, but it doesn't tell me which one is which. How can I tell?
I think I have the right one, because when I checked it, there was oil in on my socket. If the spark plug is bad, could oil end up backing up into where it is?
Thanks in advance!
have the same problem?
