Re: Rough Idle on 92 Passat 16V
That system can be difficult to diagnose as it requires special gauges & test harnesses. You can remove the rubber boot from the top of the air flow meter & clean off any oil deposits. If you have a multimeter you might want to check the coolant temp sensor located in the upper radiator hose flange to the cylinder head. It should read about 2-3000 Ohms cold & go to about 2-300 Ohms at operating temp.
