If it's now running right, great! But....

The sender on the _top_ of the tstat housing is for the temp gauge and
overheat light only. It shouldn't have anything to do with running issues.
The sensor on the _bottom_ of the housing, however, is for the computer.
That could cause problems. If you end up testing it, beware of the the wire
path. The two wires cross inside the plug. Very odd.
