Hi Pandaa

You have an engine emissions fault.

This can affect the fuel usage/emissions of the car. The ECU has reported too much fuel is being injected (rich) for the amount of air taken in.

You also have a problem with some engine electronics :(

You should take the car to a mechanic that can diagnose the reason and offer a repair. Someone who knows your engine well :)
