What would happen if your catalytic converter went bad?

This does not seem to be the cause of a bad catalytic converter. A converter is there to convert harmful toxins into harmful ones and you will know if it goes bad if your gas mileage suddenly worsens or your RPGs are going up but the car does not go any faster. If your car is sounding funny and has an odd smell, then it might be something to do with the heater core.

How do you change a Volvo 240 catalytic converter?

Working on the exhaust system is a job best left to a professional. You will save very little by doing it yourself. Have the catalytic converter tested to be sure you need a new one. Catalytic Converters are very expensive so you do not want to replace a good one. If it is bad you need to find out why it went bad. Things like a miss on a cylinder from a bad plug or a defective O2 sensor will ruin the converter. Also a burnt exhaust valve will destroy the converter.


Will bad ignition coils cause the catalytic converter to heat up and go bad?

Yes. If a coil is bad causing one or more cylinders to not fire, this allows raw unburned fuel to enter the catalytic converter, where it is burned. This can ruin a converter.
