high idle

My 89 190e 2.6 is idling between 1500 and 2000 rpm. I changed the ICV,no change, no codes, and if you unplug the ICV the idle drops to 1000 rpm.
not sure what to check next.

There is also a "Thrust Cutoff Switch" under the air cleaner that could be the culprit.

My micro switch was fine. it was a cable adjustment problem for mine. I turned the cable adjustment (white plastic adjuster on my 300ce) a few turns, and it idles perfect now. but, still could be the switch on yours.
