Please check your throttle linkages. When you press the throttle they may be getting stuck in that position. Enter your engine bay and move the throttle back and forth and see if there is some resistance and any particular area it may be sticking. If it gets stuck, get some grease and grease where the linkages meet. They will be very easy to move and they shouldn't be getting stuck.

If that does NOT work, then please click -->this<-- for more information on high idle problems.

Have you tried a forum search? The archive has a wealth of information.

Please click 'User CP' on the top tool bar, and complete your profile with a location and model of your car.
It makes it easier for members to offer advice. MB produced different, and region / Country specific versions of our cars.

Welcome, to take advantage of all the forum features, please re visit the 'Welcome to the Forum' tutorial sticky on top of the W126 page, as well as the two DIY stickies.
It will show how to search the forum (3 words min.), and has a link to the Russian MB site where you can run a VIN#.
Cheers
