Eratic idle, 190E

Vadrill. Have you checked the throttle butterfly valve return spring? This is in an almost inaccessible place beneath the inlet manifold, and sometimes has a habit of unhooking itself from the "inboard" arm of the butterfly valve.
I had all sorts of problems with idle speed and smooth acceleration until I discovered that the spring on my 190E 2.3 was missing altogether.
