2003 TJ Sport 4.0 misfiring and code P0353

[Jerry Bransford]

Thanks - these are the new spark plugs that we just put in. They seem the right ones?

The one that were fit previously were not the right one and since I just got the car no one realized.

I wish @Wranglerfix could fix mine, but I'm in Australia.

That model spark plug is fine. No excessive antiseize on the plug threads right? That stuff conducts and will cause misfires if it accidentally makes its way to the electrode.
