View Full Version : '91 Passat Idle 'hunts' when hot

Hello everyone!

My newly acquired brilliantly kept Passat runs and drives excellent. I'm in northern ontario and it is not uncommon to have -30 degrees Celcius average temperature. The engine starts instantly and runs very smooth until warm, then the idle begins to hunt between 800 - 1100 RPM. Does anyone have any ideas about where I should begin with this problem?
