I have a feeling whatever is causing this is something that’s not so obvious but will make sense once it’s found. It’s just finding it that sucks.
We're gonna have a good laugh when we find it, as in THAT was it!.
Check out this article, this guy was having the same issue I was having except he was having problems with cylinder 6 and he had his computer throwing a miss fire code. It ended up being a broken valve spring on cylinder 6 and the tech said historically it’s cylinder 8 that has issues with the valve springs.
