I recently had the whole throttle assembly out of my van, trying to get the switch to adjust. I found several problems, all inter-related. The cam actuator for the switch had so much wear, it could not be adjusted out. The throttle shaft wobbles in its bore. The contact face of the switch itself was worn - badly. The remedy for the wear on the actuator face of the cam was good old "gel" superglue. I used that to carefully build the profile of the cam back up, so it could be adjusted as needed. I first tried soldering a shim to the switch, but found out the little arm is stainless steel. Drat! As for the Shaft, well, I am just stuck with it...

If it is adjusted too far one way it will not idle when cold. When it is too far the other way, it dies when you barely press the accelerator pedal. Does anyone have any hints for adjusting it properly? I followed the Bentley, but It's just not staying there. I think the cam may be worn becasue it is very touchy to adjust. I assume the cam is replaceable without having to buy the entire switch assembly.
