If the needle is swinging wildly back and forth, the culprit is possibly a bad temperature sending unit--as long as you're sure the temp is okay. I assume it is doing this just when you turn on the car, and it hasn't had a chance to overheat?

if u sure the temp is ok then the temp switch/transmitter/sender has failed. i am not familiar with these engines but u r looking for a device screwed into the engine block with a wire petruding from it going to the engine management or directly to your gauge.
you need to change this its a simple bimetalic strip inside and they do fail.
sorry bit vague not my expertise but hope i sheded some light

Change the temperature sensor on the side of the engine block an easy job when you have the new sensor you will know what it looks like

If the wire from the gauge to the sensor shorted to ground it would make the meter peg.

it could be a faulty thermostat. Or it could be a faulty temperature sensor on the side of the block.

probably a faulty sensor. take it to the shop before you cause damage. it also could be a stuck thermostat.
