Started with 0420, diagnostics said Bank 1 sensor 1. Changed and code returned within a week. Changed bank 2 sensor 1. Car started misfiring and codes p0032 0420 0456 0300 2314 0108 0123 0222. Scan showed cylinders 1, 3, and 5 misfiring. Changed #5 coil (easiest to get to for troubleshooting) no changes. Took for full diagnostics. No vacuum leaks, 100% dead-on compression test. All plugs/coils in good order. No conclusions for all these codes. Reset pcm, misfires stopped for a week and car ran fantastic, better than when I left the dealership. Then many codes showed up again; 0032 2122 2127 0013 0010 0020 0118 0123 0222, plus U1400.
Ordered new PCM and installed as that was suggested culprit (discovered 2013 Charger 3.6L commonly has PCM failure around 75K miles). Now only code that remains is p0032, no misfires, cant clear the code either. So I took OEM sensor back for warranty replacement just in case. Still can't clear this code and last option is the dealer (which I really can't afford). I'm honestly about to just voluntarily repo this car I don't know what else to do.
