Got a misfire on cylinder 1 CEL.
Just threw these old SP542 plugs in 2700 miles ago and they’re this bad. The back two cylinders had oil around the bottoms of the plugs. These were gapped to around .30. The new plugs are around .28. Hoping this cures the misfire issue. It was only misfiring at higher speeds under heavy boost.
I’m running the Cobb accessport with their canned tune. Wondering if it’s too much?
