I had the same problem Keith. I replaced both my O2 sensors and still had a code 32. I know I had too much unburnt fuel out of exhaust because my problem was a dead ignition coil on the right bank. That obviously caused another problem, a dead cylinder and a rough running engine. You might have a problem with a coil on the drivers side, or as SoLCaL LS-L said - a faulty injector on that side.

Yours might not be bad enough to cause a noticeable stumble in the engine, yet.
