How long have you owned the car?

 

I always check the gap beforehand. They were to spec. Was running iridium 9s before and thought that was the issue. It wasn't. I've owned the car for 6 months ish. It's so strange how it goes away after 2.5k rpms and doesn't really do it when cold either. Since she is retired on Monday I might pull the head and check what's going on there?
