P2099 Fault Code

Hey guys,

I received a fault code P2099 (Powertrain Post Catalyst Fuel Trim System Too Rich bank2) on my OBDII. I had this fault a few months back and cleared it and everything was good for a while. About a week ago it came back (along with the check engine light). The check engine light will be on sometimes and other times it will be off (without me clearing the fault). Any advice or help would be much appreciated.
