This is something I don't have the courage to unplug. It is under the black protective cover with the throttle body.

There is a rubber pipe extending out of the top of the vacuum tree. half inch in diameter. Leads to a silver round thing about 2" dia and 5" long with a connector on one end. There is a second pipe that loops around and seems to T into the air intake pipe at the throttle body.

What's that thing? Has an electrical connector on it.


BTW. The half-inch diameter pipes seemed in good shape on this 1998.
