I have an 02 Limited 4.6 V8 that I bought in October. A few weeks ago I started getting P0138, 132, 1132, 300, 301, 304, 172 codes. I replaced the bank 1 upstream 02 sensor and all my problems were solved. Until I replaced the bank 2 sensor (I'd heard that it's best to replace them in pairs) a few days ago. Now I'm getting the exact same codes, all on bank 1 as if I'd never replaced thought 02 sensor which may not have been my problem to begin with. Ignition coils are okay on the misfiring cylinders and I'm stumped.
