Slight mis at idle

[zachggus]

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?

Finally fixed it ended up being a bad coil. I replaced all of them half were original 15 years old. Runs like new again.

How was the rebuild process? What lead up to it and what all got replaced? I've done the water pump and timing chain tensioners, but not sure I'd want to tackle a full rebuild (been a long time since doing one on an Alfa Romeo GTV6).
