The normal mechanical throttle cable works fine.

Even weirder...my vacuum pump, which has never worked at all since I got the car, is now running!!! WTF?
This is for your cruise control and is vacuum operated. It does have a cable to the throttle body and should operate the throttle when squeezed.
