Hi there
We are having problems with the engine light coming on and staying on for a while (days) and then going off - so very intermittent. Car is still going well and no issues. We were told that it was probably the catalytic converter - can you just replace the sensors - will this stop the engine light coming on?

Hi there,
I recommend you take the car to a technician to carryout a diagnostic check.
The code generated from a check light could be a fault of any one of a long list of operating systems, the ecm is responsible for monitoring.
Definately don't replace any sensors till the fault code is read, and the associated system has been tested for a fault. Whether it be a sensor fault or a componant failure.
