the odd thing about the misfire is that after I warm the engine up, if I shut it down and restart it and take of quickly without letting it sit for a while, the misfire will stay away if I keep the engine above 2,000 RPMS. That is kind of weird. I am considering taking it to a pro for diagnostics so I really don't have the support, knowledge and backing to dig to deep into this.

I believe the thought of an issue with carbon might be the problem. Were I to actually have a burned valve, a bottom end issue or a VANOS problem I don't think it would clear up with keeping it above 2,000 RPMS.

Anyone have any suggestions before it goes that route?
Did you ever figure this out? I'm having an almost identical issue
