Hello to you all, need some direction on what to do.  Just removed my throttle valve switch on my 87 Vanagon with 2.1 engine.  My question is relatively simple but i was wondering how you list members reassembled unit.  Does one put a small amount of grease on the plastic cam / metal arm that actuates the switch or should it not be lubricated and left dry?  Not a big deal but i am curious on what would work best.  Thanks in advance.
