I've got a 2014 ram 2500 6.4 hemi with 135,00 miles that keeps tripping the check engine light for bank 2 lean condition. All 4 o2 sensors have been replaced, there are no leaks that I can find and I've replaced the spark plugs. The local dealer isn't much help other than telling me my muffler is the problem, I had a reputable exhaust shop check it and the cat, both are good. Please help
Please post the exact code + definition you're getting.
It's very likely it's been answered on this forum before so try the search box on the right hand side.
The web page obd-codes.com is also very good for providing troubleshooting guidance.
Follow what Scotty does in this video and go from there. You can get a small pair of CRC MAF and Throttle Body Cleaners at Walmart for $10. This might help if both banks are running lean.
