If it is glowing red it is partially clogged or the engine is running rich.
There's no possible way to pass inspection with a bad catalytic converter, if if you find out you have a bad catalytic converter during your inspection you have a chance after you after you have replaced the catalytic converter and the inspection no no charge/free!!
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
Transmission torque converter or an exhuast catalytic converter?
A bad coil can damage a converter. If the engine is misfiring, it will cause raw fuel to get into the converter and that can cause failure.
A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
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.
A bad catalytic converter will cause a severely restricted exhaust system. You would notice a lack of power and performance from you vehicle and in cases of a completely blocked converter, the engine may not run.
Yes it is possible.
They can become clogged or they can burn out.
No.
Yes it does.
Loss of power and mpg. The check engine light should also come on. the check engine light will not come on if the catalytis converter is going bad..it will however get very hot and start to glow red. The check engine light will illuminate with a bad cat if the vehicle has a post catalytic (downstream) O2 sensor.
