Hey all,

So I have owned my 2000 CLK430 for about two days now, and today I noticed some problems at idle. It is not too terribly bad, but it is enough to raise my eyebrows. When I am at a standstill, the engine gidles up and down and the RPM needle moves up and down just slightly. Along with the the temp guage moves up past normal. Once I start moving, everything seems fine, and I hear nothing wrong. Any ideas? I am going to look at the air filter once it stops raining, but I am not sure whether to bring it back to the dealership where I bought it at and use my 30 day warranty or to drive the 50 miles to the Mercedes dealership and pay out the ying yang. I just don't like the idea of a Kia dealership working on it (thats where I bought it). thanks in advance to any suggestions.....

try cleaning the throttle valve first which is the only thing that you can do.

if dirt blocks the air, the control unit will open it more to compensate and close it down when the idle get a bit high... hence the up and down idle speed.

faulty airmass sensor can trigger the same problem.

 

thanks. im gonna bring it back to the dealership where i bought it from, and use my 30 day warranty. i'll let them know to check that out. thanks again
