Idle speed increase question

My 190D and I were going for a spin when the throttle went to wide open at a red light. My foot was on the brake when she did this. I've checked The shop manual and it makes mention of a Idle speed increase actuator. I could understand burping the throttle to prevent stalling but this thing floors it. (It started spinning the right rear a lil'. I got a bit misty eyed). Any ideas on where to go from here.


Thanks
WG

First thing is disconnect the cruse control linkage. I believe that is the only thing that can cause that much difference.

The cruise is/was disconnected. I'm studying the IP controls/specs to see what would cause this. there is not any binding in the linkage. It's happening within the IP.

I thought I read something last night about a bad voltage regulator can cause that. Something about wild & uncontrolled idle changes.
