Thank you for your careful explanitions on this CIS system. Its been too long since I have worked on them, plus I am having a "high idle when it (85 500SEC) warms up. I figured it was the stepper control module. But now I am going to give it a good going over on the areas you touched on.
Excellent. I feel I am finally getting to understand both the basics and the importance of the maintenance of the vacuum system on theses engines.
Excellent tutorial of the idle control system .thank you
Thank you sir for sharing your knowledge with other MB enthusiasts!

When I had my 85 380se the cold idle would be just under 2000rpm. Any guesses ?
