* A lean fuel mixture. This means that there is too much air and not enough fuel in the engine. This can cause the catalytic converter to overheat and turn red.
* A misfire. This means that one or more of the cylinders is not firing properly. This can also cause the catalytic converter to overheat and turn red.
* A faulty oxygen sensor. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gas. If the oxygen sensor is faulty, it can send the wrong signal to the engine computer, which can cause the engine to run lean or misfire. This can also cause the catalytic converter to overheat and turn red.
If you see that the catalytic converter on your 1997 Crown Victoria is glowing red, it is important to have the vehicle inspected by a qualified mechanic as soon as possible.
