Can A Bad Catalytic Converter Make My Engine Light Come On And Off


Question: Can A Bad Catalytic Converter Make My Engine Light Come On And Off,
Other than bad catalytic converter, the car is in top condition. Head gasket etc all replaced.
I’ve just had head gasket replaced and all the parts associated with it.
Another thing that could be helpful is that my car does not idle at the right revs. it’s either too high, or too low.

Best answer for Can A Bad Catalytic Converter Make My Engine Light Come On And Off

The computer flashes the light on and off (not a steady on light) when the engine is dumping unburned fuel into the catalytic converter which will ultimately burn it out due to the high combustion temperatures caused by the unburned fuel. See the details in the technical note below. The engine problem must be fixed when a bad catalytic converter is replaced.
