P0172 (bank 1 rich) is caused by fuel pressure too high. Perform fuel pressure test. Leaking fuel injector(s). - Perform pressure leakdown test. Vacuum leak around the MAP sensor grommet. Oxygen sensor contamination, restricted exhaust or air intake. Fuel Vapor Canister saturated with fuel. The P0420 90% of he time is due to plugged up catalytic converter but if you want to try to replace 02 oxygen sensors first but most likely is the catalytic converter that's why you're getting the P0172 and P01133 because it can not exhaust. Need to have it scanned with live data scanner. Time for a new catalytic
