The ambient temp sensor is at the top of the driver side front wheel air
duct. 
Chances are the connector has popped off.

You did not quantify the problem (how much the revs stick and for how long),
but if I remember correctly, the DME intentionally keeps the RPMs from
dropping like a rock to help with engine/gear speed matching as you take 1/2
second to upshift. If the RPMs stick indefinitely on a warmed up car, or
stick randomly, try lubricating the throttle linkage on top of the intake
manifold.

Are you sure it is leaking?
If so, trace the brake plumbing from the fill container to the ABS pump to
the wheels. Look for damped/oily dirt areas near the connectors.

If the level is dropping, do yourself a BIG favor and find the leak. When
the leak eventually accelerates into a flood, you will loose the brakes and
discover impact braking.
