Has it overheated lately?
My wife overheated our Galant and it just stopped working, it cranks but that's it.
I pulled the sparkplugs and found them wrapped in a gewey jelly like substance. Like an oil/antifreeze combo.
I am going to replace the entire motor for $1000 as taking it to the mechanics to theorize and practice may cost more.

I have the same vehicle, same code P0421, changed the BOTH O2 sensors and the check engine light was still on, took it to my fathers garage and checked the Catalytic Converter, and it was ok later I found out that P0421 means that the vehicle doesn't have the proper mixture of gas and air (running richer) so I changed the MAX air flow sensor and wala the code went away.

Im pretty sure the bank 2 is talking about by the catalitic converter and since is sensor 1 it should be before the CAT otherwise it should be on the exahust manifold prolly in the back of the engine.

Pretty sure they are a 3 wire for the galant and they are located at various stages in the exhaust pipe. The look like this if you havent seen 1:
