Stomp codes reported are for oxygen sensors, might be time for their replacement.

if an o2 sensor is going bad what would excatly happen. my right cylinders dont worl sometimes and its telling me that the right oz sensor is bad or somthing else. and than sometimes after an hour of driving it will run on 8 again and have a huge differenc. keep in mind that there is an o2 s for each bank of cylinders not 4 like most cars

Thank you, you added to the diagnostics and we have a drive-ability issue, yes? Is there anything about the history that might help us here, it sounds like the regular stuff like, Is there oil in the spark plug wells? Plugs OK? Check that and let us know
