'88 300E Sometimes Idles Too High
 

Intermittently, the idle won't kick down and stays somewhere between 1200-1500. I have to put in neutral and give it some gas, then it will usually kick down to about 600-700 after 1 or 2 tries. Is this electrical, or mechanical?

Thanks,
Ray

Behold the TVS three pole connector on the front/top of the inlet manifold when you remove your air cleaner.
