2008 GMC W3500 Forward W3S042 6.0L MIL Lamp on
Thank you for all the replies. I ended up putting the downstream O2 sensor in and it cured the rich code. It was just over the threshold for Lazy territory. The vehicle did however come back with a P0430 code, so it will be getting a convertor also. Trouble codes: P0172 (Fuel Trim System Rich Bank 1), P0430 (Catalyst System Low Efficiency Bank 2).
