Hi there,

This code is for the bank 2 catalytic converter. If the converter is plugged up it will cause starting and running issues.

Try taking the O2 sensor right out of the exhaust manifold on bank 2 and see if the issues improve. If they do, then you know the converter is plugged up and needs to be replaced to resolve the problem
