Question Check engine light 0420

replaced cat and both o2 sensors
after resetting light drive car for an hour then
then the light comes on again.
the water temp seems low when the light sets.
water temp stays on the first 1/4 then almost drops to blue band.
what does your water temp read under normal conditions.
thanks

Temp gauge should at the half mark....always.
Replace the thermostat......if you haen't replaced the water pump or radiator(optional), you might as well do it too. Our thermostats are designed to fail open, so keeping the car's coolant flowing at all times. You may notice that your car is slightly quicker, because the ECU senses the car cold and runs it slightly richer.........this MAY be the CEL issue.
Good LUck and keep us updated.
