So code P0175 indicates the engine is running rich on bank 2, passenger side, of the engine. Do you mean that gas got into the engine oil? If so, you will need to do a oil and filter change before anything else. Also, make sure there is no fuel residue on or near the spark plugs when you start the engine. After changing oil, you can clear the code and drive the vehicle to see if the code returns. If you have a scanner that reads live data, you can watch SHRTFT1 and SHRTFT2. They should read about the same and switch + to - around zero within a few points. I hope this gets you started, please let me know what you find or if you have any more questions.
