Hello everybody,

I know that he idle control valve is a reccurent topic. I did a search but did not find the right answer.

So my question is for an 1989 300 CE 6cyl.
I would like to know if the ICV is cleanable and how to do it.
Or perhaps it's better to have a new one ?

Thanks in advance for your answers, and be lenient because english is not my mother langage.

Best regards

using some information from this board, I cleaned the idle control valve on my car by removing it (you have to remove the air cleaner housing on my car, a 1987 300E, to access the valve) and squirting a bunch of carburetor cleaner into it and shaking it repeatedly (cover the ends with your fingers while shaking it). If you can hear valve inside freely moving back and forth when you shake it, you probably don't need to replace it. If it is dirty, it should be moving more freely after you clean it.
