everything is bank 1, pass side.

On the header is a small bolt it is right in the tube for cyl 2 before the 02 sensor, that is what I removed. Tried 2 different o2 sensor tools and that thing isn't budging right now. It's going to need some heat cycles to break it free.

Not only do the misfires increase, they reset themselves to 0, and never throws a code.
