Cyl. 3 misfiring - what to do?
I have a 97 Cougar XR7 8cyl. The other day it started running rough. The next day the check engine light came on. I had the code read and it has several "Cyl. 3 misfires".
Which cylinder is # 3 ( I bought a plug to replace )?
If it is the plug, what could cause it to go bad (their about 2-3 years old)?
If it's not the plug, what else could it be (Besides the plug wire)?
Thanks for any help!
