Answer 1

Hi there,

It sounds like you have a misfire on bank 2. This could be due to the catalytic converter breaking and blocking some of the exhaust flow, or you have a bad ignition coil causing a misfire and damaging the converter. I would start by lowering the exhaust and checking the converter for breaks and blocage.
