Need help with code P2099 bank 2 System Too Rich?
2012 Camaro V6 76000 miles no modifications besides a drop in K&N air filter one month ago code P2099 with check engine light came on. Replaced bank 2 down stream 02 sensor and code was clean and did not come back. Now one month later code P2099 bank 2 system too rich with check engine light is back. Recommended fix is to replace fuel injectors and/or intake manifold gasket? How can I fix this code and what do I need to replace? Is this 2012 Chevrolet Camaro V6 a lemon?
