WUR Questions...

On my 78'SC, i have a blue vacume tube from the WUR to somewhere. What would happen if i were to remove the tube?
Would the engine lean out? What if i remove the vacume tube an nothing happens?

Which vacuum line is it? Your WUR should have two, one coming down from the top, and one horizontal at the bottom. The bottom one is connected to the thermovalve. The two vacuum lines are connected on either side of the throttle body, and act against each other. If you disconnect the top one, it won't make much of a difference, if you disconnect the bottom one, then the car will run rich.
