Having problems with your 2000 Volkswagen Passat 4Motion ?

Hard idling I have a 2003 VW Passat 1.8T. I talked to a mechanic about the rough idle and he told me a couple of possible causes. The first i do not remember.... LOL..... only that it had something to do with maybe a regulator of some kind, located on the engine manifold. The second fix was to remove and either replace the mass air flow sensor or clean it. I was changing the air filter the other day and found the mass air flow sensor, but could not access it easily do to another tube running out
