Thanks Paul. I'll take a look and see what I can do.
BTW, that new throttle actuator you sent me is still working fine. I took apart the old one, and you wouldn't _believe_ the poor condition of the insulation in the control cable. I cut it open and it just flaked off in my hand. I'm working on a way to replace the cable (easier said than done b/c of the customer mercedes connector); I'll post pictures on here for everyone as soon as I figure it out.
