PLEASE HELP,what is this??
 

Hey guys,just got done replacing my head gasket & replacing guides.It seems to run fine & seems to be a sucess,(thanks to your help)My only prob is there is some kind of pump or something that has a adjustable linkage that seems to only operate when you are in w.o.t. & connects to the throttle linkage.My prob is when I hook it up the idle goes way high.It seems like the adjustable linkage piece is too long all of a sudden.Im not sure if it is ok to just adjust it or not.Thanks,Frank

Oh yeah another thing,I have a black vacuum line that goes from a 2 nipple sensor on the front of the head to a check valve then Im not sure where to.IM GOING NUTS TRYING TO FIND IT(short trip)

what year 300e? Is this thing beneath the intake manifold? That's the cruise control servo.

And the thing with the two hoses? Take a look at these pics. I shot them prioir to doing my valve seals and head gasket. On goes to a nipple under the throttle body. The other not so sure. :o

Thanks rp ryan.The pics helped me solve my mystery.I really appreciate it.Oh by the way,youre right it was the cruise servo.I adjusted it & its fine.
