[W126 Coupe] HI IDLE

[Mike Ramay]

Try gently smacking the idle control valve (ICV) with a plastic screwdriver
handle. If that makes the idle run up or down, then it has the generic
internal broken wire. If so, you have a couple of choices. A new ICV is
several hundred dollars, don't know what a used one costs, or you can fix
yours for free. 

 

Let me know if you have a broken wire in the ICV. It's not hard to take it
apart and resolder the wiring.

 

Later,

Mike R.

Hello All,

 

I just replaced the original steel fuel injectors with brand new shiny brass
ones along with new seals, holders and air tubes. Also put in new Beru spark
plugs. Engine now runs nice and smooth but now have intermittent high idle.
Tried cleaning out the idle control valve with carb cleaner with no
appreciable effect. Do I need a new idle control valve or is there another
culprit to hunt down?
