00 1.6 cutting out & erratic temp gauge. - nonmech
My car cuts out when the temperature gauge appears to stop working and goes from it's proper reading to zero. The gauge can suddenly fail as you are driving along but it only cuts out when you have to stop and the revs drop so low that it cuts out.

The other thing it does is when you start the car from cold when the outside temp is warm it will rev to about 2000 and gradually come down. Though it doesn't over rev when the weather is cold. It still did this when the temp gauge was working properly.

The most obvious cause appears to be the coolant temp sensor and i understand how the cutting out could occur. I'm not too sure about to over revving though. It is likely to be the sensor deteriating and giving incorrect readings?

Any advice or suggestions would be appreciated.

Would also like to know where abouts on the radiator this sensor is located (if that is the problem!).

Cheers.
