Bad switch, or conceivably a short in the switch harness.

You can try squirting contact cleaner around the switch actuating pin
and then exercising the switch, may have to peel back the rubber boot
to get to the pin.  You want the stuff that leaves an oily residue,
Radio Shack has some.

You can see from the construction which is the closed-throttle switch
and which is the W-O-T switch.  Either switch may be the shorted one
if there's no mechanical reason for one of them to be closed.

Push come to shove,, run without them while you figure out what to
do.  It doesn't bother the 1.9l behavior at idle much, it's mostly
for deceleration shutoff which you won't notice the lack of
particularly.  But remember that you don't have full-throttle
enrichment so avoid full throttle to obviate any possibility of
overheating the cylinders from lean burning at full throttle.
