Codes P0300, p0175, and p0172, 17 seconds after ignition?

This looks like you have a fuel injector leak or excessive fuel pressure. Can I ask how the engine is running also if you pull the spark plugs out what do they look like? Here is information on the codes:


P0300: Random/Multiple Cylinder Misfire Detected

P0175: System Too Rich (Bank 2)


P0172: System Too Rich (Bank 1)

The fuel pressure should be 58 psi +/- 2 psi.

Also, sometimes when injectors get cleaned it makes them stick open so they may need to be replaced. These codes are telling you the fuel consumption cannot be controlled.

The fuel pressure regulator is located in the fuel pump module assembly and is non-serviceable. Please upload images of the spark plugs once they are removed. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Here is the latest freeze frame data.

Thanks for the readings, it looks like you have a bad ground or the PCM is bad, these readings are all over the map. I would check the ground to the engine and chassis. Also, make sure all of the engine grounds to the main engine harness are clean and tight. Here is how to change out the PCM in case you need it. You can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what you find.
