Hi, Happy Christmas everyone. I have a 2003 CL 55 Amg Kompressor that is idling really fast (2500rpm). Plugged in a diagnostics machine and got a code saying it was the idle control valve. I cleared the codes and it ran okay for about 3 miles then went bad again. I`ve been told you can remove and clean these to fix the problem. My question is...Where is it? and how hard is it to remove? and what do I clean it with? Thank you for any help.
