No reply. Doesn't seem to be interested in solving the problem.

P0170 202 Fuel Trim (Bank 1)
This is a general translation but there are thousands of different codes for various years engine codes & ecu versions & software! You really need to graph live data or scope sensor, it could be due to air leak in exhaust on that bank or even a fault in DME
