COP replacement?
Good afternoon group,
I developed a significant miss on my '00 Excursion 6.8L yesterday and threw a P0306 code. Since the engine has 178K showing and I bought it used, I am planning to replace all the COPs and plugs.
Does anyone recommend one COP over another; motorcraft over Accel, etc.?
Any preference for spark plugs?
Thanks in advance,
chardagha

Chardagha, consider replacing only those cop(s) that need it. Many here have original cops with no issues after more miles than yours. I keep 2 new Motorcraft cops in the tool kit as needed - they're easy to replace ('cept #5).

That's a waste of money. Find out what is causing the miss first. It might be something as simple as a COP boot that needs to be replaced. Don't throw parts at it.

Motorcraft pkugs, boots and spring kit. Anti-sieze, die electric grease and a torque wrench and you should be good to go.
As others said only replace the COP that needs it.
