P0175 - Fuel System Rich

P0152 - 02 Sensor Shorted To Voltage

I think you have an issue with an oxygen sensor shorting and causing the system to go into a loop. When that happens, it causes the computer to run the engine very rich. That can cause a misfire. Have you checked the oxygen sensors? If you have a live scanner, check how they are reacting with the engine running.
