Best Answer: When a catalytic converter goes bad it will restrict the flow of exhaust gases through the exhaust system. Basically, if the exhaust won't come out easily, air won't be taken into the engine easily to mix with the fuel to be burnt and give you power.

Example: an ignition coil that is not working will quickly ruin the catalytic converter if the engine is allowed to run more than a few minutes misfiring.
