2005 Audi A4
I have a 2005 Audi A4 and it is idling rough. When idling it almost has a slight rattling sound, I have heard that sound in other cars especially German ones. What does it possibly mean?

Engine running rough or misfiring can be cause by the following:
1.Defective spark plugs
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
8.EGR valve that is leaking.
10.Throttle position sensor.
11.Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve
Note: If it doesn't apply disregard it-
