Default Idle speed goes up & down
Got a 96' E320. When we go to the cabin in the mountains (3000feet altitude), the idle speed seems to go crazy, and varies from 500 to 2500 rpm, goes up and down like crazy. If I kick the pedal a few times, it settles for a while, but goes crazy again after a minute.

What is this? Kind of Air Mass Regulator broken? Expensive?

Thankful for any tips.

Cheers
Pal
