The Temp I sensor on my '84DL (1.9L gas engine) appears to have gone "crazy"
with the advent of cooler weather here in the Deep South.  After about 1
minute after the engine is started, temp needle moves to mid gauge or
higher.  Then sometimes it will drop to almost dead cold.  Is this typical
of a bad sensor?  Coolant level is high enough to keep the flashing LED off,
but I am probably a couple of quarts shy of full.

If it is a bad sensor, any "gotchas" on removing the old and installing a
new one?
