I’ll take this into a mechanic next week, but yesterday my check engine light came on. My car is driving fine but this was the error code. “P2099 post catalyst fuel trim too rich bank 2” Google tells me it can be a list of things. Just wondering if anyone has had this come up. The guys at autozone told me to use a fuel system cleaner as a first step but I’m not trying to mess anything up so I didn’t get one.
thank you
