I have a vw polo yr 01, ALD engine 1.0cc. When I start in the morning, I get a fuel smell from exaust. Moreover it's difficult to run immediately. I noticed that when tempereture reaches 35degree, all come back to normal. Please help. I have changed my spark plugs too, and no error found while scanning

Probable causes of an engine running rich are as follows:

1. Fuel pressure not within specs. Can be cause by restricted fuel return line or defective fuel pressure regulator.
2. Defective Oxygen Sensors.
3. Leaking injectors.
4. Coolant temperature sensor out of calibration.
5. Restricted air intake system.
