I have gas in my oil my car stalls has rough idle misfires it throws codes P0137, P0131, P0304. I have changed O2 sensor, MAP sensor, upstream and downstream stream sensors, spark plugs, and coil packs. I have done fuel assembly replacement. I have changed injectors. I have changed the power control module. I also changed oil pressure sensor because it needed it, but after doing these things it still throws the same codes and acts the same. i don't know what else to do a local mechanic shop charged me $1,000.00 to fix it and that's after I done all the other stuff to the car and they just must have seen an easy target thinking because I'm a girl. I don't know about cars because they have it back doing the same thing on, and Engine light has been on for about a month now it's blinking. please help. oh, and I had oil in my power control module when I took it off and on my spark plugs.

These Oxygen Sensor codes can be caused by the P0304 - Cylinder 4 Misfire Detected.

P0137 - Oxygen Sensor Circuit Low Voltage (Bank 1, Sensor 2):

P0131 - Oxygen Sensor Circuit Low Voltage (Bank 1, Sensor 1):

P0304 - Cylinder 4 Misfire Detected:

Can I ask you how the engine is running? Can you please shoot a quick video with your phone of the engine running under the hood? That way I can tell for sure what's going on. You can upload it here with your response. From what you have said it only leaves low compression or a fuel injector. Here is a guide to help check the compression and if that is okay to change out the fuel injector in the images below.

Check out the images (below). Please let us know what happens.
