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
\015\012Are you ONLY using premium gas every time? If not, try only putting premium gas for the next 2 fill ups. See if you see a difference.
