I Changed My Spark Plugs/Wires In The Middle Of September and Now I've Got An Issue.

The Car Began To Misfire Recently. When taking off from a standstill, the car will stutter and then resume accelerating normally.

I removed all 8 plugs today(Champion Plugs Gapped @ .40) and the heads of the plugs were coated black. There was liquid oil on Cylinder #7's Spark Plug.

I'm getting 8 New Plugs Tomorrow and Seeing If That Fixes It.

If not, then I'm guessing my rings are toast? If that's the case, how much $ do ring swaps generally run?

Any other ideas/suggestions/comments?

 

A few questions:
Why are you using champion plugs and why are they gapped at 40? Don't see your mods listed but stock gap is 60

What makes you think rings are bad - are you burning oil?

 

Get rid of those plugs and get some NGK TR55s and gap them at .45.
Liquid oil on the plugs is a bad sign and can more than likely be bad ringlands.

 

Tr55 gapped at 55.How many miles on engine?Are you sure its oil and not gas?Not trying to make you look stupid just looking for more info.

 

Got Some TR55's and gapped them @ .60

Misfire Is Gone.
