1990 W124 idles very high - adjust how?
This had been intermittent idle speed problem , ranging from 600 - 1500 (it would oscillate) but now has settled out at 2000 RPM. I need to set a the correct spec which is what, about 700 rpm or so? How is this done please?
Could this be vacuum problem or fuel air mix? I don't understand this system yet. Can anyone assist please?

high idle
this car is new to me. How do I identify the vacuum lines? Is there a schematic or something else on line? I'm familiar with common rubber vacuum lines, but see a lot of thin plastic hoses/tubes on the engine. Suggestions?
