So I recently had an aftermarket cat-delete downpipe removed and swapped for my OEM as it was tripping the CEL and led to some misfire as well. Come to find out there was an air leak between the DP and turbo inlet. Problem went away, I switched all my spark plugs out and about a week later it started to misfire when accelerating right around 2000rpm. I suspect it may be the coil packs but not 100% sure. Any thoughts?
