Cyl. 3 misfiring - what to do?

523 Views 2 Replies 2 Participants Last post by  setfree
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".

My questions:

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!

Plugs are about 4-5 years old

My plugs and wires are about 4-5 years old. There's maybe 40,000 miles on them. I put in good quality plugs nad wires when I did them.

Thanks for the info on which plug is #3. Hopefully I will get a chance to look at it tonight.

Thank again!
