hi guys!
my car is idling too high. varies from 1200-2000. i removed the top hose of the icv, cleaned the valve and made sure it is smooth. but i still runs the same. when i tap the icv the rmp varies. so i know that the icv is the culprit. my question is can it be cleaned? is there an easy way to remove the bottom hose. and also when i give a direct current i hear a click sound. pls help

The ICV can be removed without a great deal of trouble. The bottom hose is a little bit of a pain to get back on but not to bad. You can use several different things to clean it with but the last time I cleaned mine I used carb cleaner and then let it set to dry out real well before I reinstalled it. If you are not sure how to take the ICV out you can always get a copy of the w201 manual from the FAQ section to guide you through the process.
