P2097 Post Catalyst Fuel Trim to Rich Bank 1
Hi!
I have this code, and I researched it on here. Basically I already replaced the plugs and rear o2 sensor trying to make the car run better, but I can't seem to get rid of this code. While searching I noticed people saying the adaptive something needs to be reset in the ECU, and nothing else will fix this. Is this something commonly done by the dealerships or small repair shops? Does anyone in Fort Worth or Dallas do this, so I don't go through the hassle of going to a dealer that isn't aware of the specific issue?
Thanks!

Can't help you on the reset procedure but the code simply tells you that the rear Oxygen Sensor is reading a rich fuel trim. You didn't need to replace the rear Oxygen Sensor. There are many reasons why it's running rich... faulty injectors, leaky exhaust, faulty front (pre-cat) oxygen sensor, mods.
