On my '95 Ciera, the temperature gauge will be reading normal (middle of range,) then will suddenly bounce very rapidly back and forth toward the hot end of the range. After a couple of seconds, it will return to reading normal. I noticed the same thing happening the other day after I had only driven a mile or two and the engine wasn’t yet up to normal temp… I’m guessing that it may be a malfunctioning temp sensor, or could it be just a bad electrical connection? Any other ideas? Your input is appreciated. 🙂 ---

Check the coolant level in the radiator (when it’s cold), then clean and tighten the connection at the the temp sensor. If that doesn’t work, try a new sensor. ---

Coolant level is OK. I’ll check the commection when it stops raining. 🙂 Thanks!
