small problem after cleaning idle control valve.
I'm from Bethesda, MD and I have a 1990 560SEL with 130,000 miles on it. I have looked at the threads and used search feature. However, after all the helpful advices posted I decided to clean my idle control valve with carb cleaner. Prior to cleaning my idle was 750-800rpm on a warm car and it was shaking i could even see the passenger seat shaking as well, but now after cleaning the idle valve and spraying some carb cleaner on the plate (that goes up and down) the car idles at 950rpm and then goes to 1000rpm and then stays there. The shake went away and the idle is smooth but rpm's a bit high. Once i put it in Drive or reverse rpm's go to normal 600-650 and runs smooth. can you throw some ideas at me? any help would be appreciated.
