Hi, my name is ***** ***** is usually caused by a bad intake manifold gasket on that bank, have you checked the gasket yet?
I tried to make the phone call, but it said your credit crd payment failed?
if you can get some carb cleaner, then hook your scanner, and spray the intake and see if the bank 2 richens up, if it does, then replace the manifold gaskets, we do alot of these for this concern,Tim
A bad fuse will not cause the bank to run lean, nor burn up electrodes on the plugs, a vacuum leak can and is most likely,Tim
