So I just rebuilt my motor and have been driving a couple weeks. I notice when I’m sitting in traffic that I have a misfire. It’s not bad enough to throw a code and the scanner I have does not show a misfire monitor. Off idle it doesn’t miss a beat and is smooth. I was experiencing lean on bank one but I have got that fixed. I replaced both cam and crank sensors. And put a new intake boot on. Anyone had this before?
