Does the cat get up to temperature OK and not show any signs of overheating?

Note that the temperature guage on these cars are corrected to display 90 degrees when the actual coolant temperature is between around 85 degrees and 105 degrees.

Number of things it could be;

- Thermostat stuck open

- Temperature mixer flap stuck

- Airlock in heater matrix
