Loss of power, poor fuel mileage, converter gets red hot, possibly check engine light will come on.
replace sensor,catalytic converters smell like rotten eggs when going bad
the shop I go to said that my 2000 Jetta would not pass the smog check when the catalytic converter went 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
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.
A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
have it scaned by a snapon computer it will tell the bad one
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.
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.
