2010 Fusion Sport Misfires

I installed the new Motorcraft plugs after checking the gap and put the old coils back in. eBay reimbursed me for the fake coils. I drove it to work Friday morning and only noticed one hiccup (miss) on the 20 mile drive. Didn’t miss at all on the way home. Fingers crossed it was the Autolite plugs that needed replaced.

I'd be curious about misfire counts

Autolites bite again! I'm guessing it was really a combination of fake coils and pad plugs, either way it sounds like you have the problem licked.

How good did you get at pulling the plenum?
