The only real way is to take it to a garage and get them to check the exhaust emissions. This only takes about 5 minutes and my local garage didn't charge me for this when I did this.
If the emissions are NOT OK, then this could point to problems with the fuel injection system as well. If the emissions are fine, then so is everything else.
replace sensor,catalytic converters smell like rotten eggs when going bad
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.
Bad Gas milege Gives a rattling sound if it breaks down Car stops running if it is totally blocked
A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
Loss of power, poor fuel mileage, converter gets red hot, possibly check engine light will come on.
have it scaned by a snapon computer it will tell the bad one
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 can you can usually tell if your converter is bad by two ways if your car is running and the converter gets red hot or if the car is cool and you hit the converter and here stuff raddle inside
