The P2098 error code indicates a post-catalytic converter fuel trim system too lean on bank 2. Since you've replaced both upstream and downstream O2 sensors on the driver's side (bank 2) and the issue persists, it's essential to consider other potential causes. Here are some additional steps you can take:
Exhaust System Inspection, Fuel System Inspection, Check for Vacuum Leaks, Inspect Mass Air Flow (MAF) Sensor, and Examine PCV System. It can be time-consuming and to do all this testing and with what you have already done not fixing it I would strongly consider taking it to a professional.

Hi there,
The causes for the trouble P2098 code include a leaking exhaust system, a bad or failing upstream oxygen sensor, or a problem in the post-catalytic oxygen sensor circuit. The usual symptoms of the code P2098 include an illuminated or blinking check engine light, rough idle, and poor acceleration. If you have already replaced the oxygen sensors, try to check for leaks along the piping and catalytic converter.
