The 306 2.0 litre cabrio is on a second catalytic converter in the spaceof 2 months. It is going in to be looked at tommorrow. However I have noticed something peculiar. I have noticed that the car has been running at low engine temp since day one. As it has been getting cold I have noticed that the coolant temp does not go above 75 degrees celcius. This morning it did not go beyond 75 degrees for the entire 40 minute trip.
I even went to the shops before, a 5 minute trip each way and it still was unable to go beyond 75 degrees. On real hot days in stationary traffic it would get to 90 or so, but has not been able to recently.
I know that until the car reaches optimum engine temperature, it runs rich. However, would this be enough to kill a catalytic converter? Or would more be required?
Your collective aussiefrog input would be appreciated.
