Usually when a Catalic Converter becomes unusable, it is usually caused by a enriched fuel system. The rich fuel mixture causes the internal catalyst to become they usually generally melted down inside. This excessive heat is built up when the engine is running in a "too rich fuel mixture". After the converter has been replaced, the automobile should be taken to a repair facility, and have them connect their electronic control monitoring equipment to your on board computer, so the reason for the enriched fuel mixture can be determined and repaired.
What else can I help you with?
What damage can be caused by driving your 2000 Chrysler Caravan which needs oxygen sensors?
destroy the catalytic converter
What kind of permanent damage could be caused by a poorly tuned or misfiring engine?
You can permanently damage the catalytic converter (if fitted) which can be costly to replace.
What damage would be caused by not fixing the catalytic converter?
If the converter is partially clogged it can cause the engine to overheat which can cause serious problems. Other than that if will not harm the engine.
What damage is caused if the check emission system is not repaired on a 1996 Cadillac Sedan deVille?
O2 sensor, and catalytic converter can be ruined. You can also cause internal damage to the engine, depending on what the problem is. Have it repaired.
What would cause a noise around the catalytic converter and up toward the motor?
most likely the converter is plugged up and caused a leak in the flex pipe
What does code p0421 mean on a Hyundai santafe?
I believe 0421 is a catalytic converter inefficiency code which is usually caused by a bad o2 sensor or a bad catalytic converter, but I have also seen fouled plugs and exhaust leaks cause this code.
What if you still have the same symptoms after changing your catalyic converter?
Well . . . you know the problem was not caused by a bad catalytic converter. You could experiment with replacing your oxygen sensors, next . . .
I have a Ford f-150 truck the engine has a miss to it and the check engine is on and then it blinks and then it stays on and at low rpms it runs rough?
I just got my f-150 fixed with that same problem. I replaced the spark plugs and spark plug wires. The blinking check engine light is caused by excess gas coating the catalytic converter sensor. If left unfixed this will cause permanent damage to the catalytic converter.
Your 2001 impala is overheating what is your problem?
Low coolant Cooling fan not working Bad thermostat Plugged or dirty radiator collapsing hoses defective radiator cap (common problem for this vehicle) system airbound water pump not working to full capacity Or, most likely, the catalytic converter has failed and clogged the exhaust and caused the intake manifold to melt. Chevy issued a letter in 2005 to this effect. I believe the letter stated that Chevy would replace the catalytic converter at no charge if the car is less than 10 years old or has less than 110,000 miles. Call your Chevy dealer ASAP and have it replaced. Unfortunately, from my experience, Chevy will not pay for all the damage caused by this catalytic converter design flaw. So you'll most likely be stuck with the repair costs for the damage caused by the melted intake manifold.
Can a 1996 Ford Taurus run without a catalytic converter where is the o2 sensor at?
Yes, the Taurus can run without the catalytic converter--it is not necessarily good for the engine, but disconnecting it will cause it to fail emissions testing. If you've seen the Honda Civics running around smoking like a factory, this is caused by no electrolytic converter. The O2 sensor could be in the exhaust pipe between the manifold and converter.
Will your 1999 Saturn pass smog test if you replace catalytic converter?
Normally when catalytic converters become clogged and need replacing there is a reason for this. Something caused the converter to become clogged. Unless you fix the problem the new converter will just become clogged like the old one. If the check engine light is not on and the vehicle is running perfectly with the new converter then it will more than likely pass the smog test.
How can you fix the Co2 on your Chevrolet Beretta its way to high?
You may have a bad catalytic converter. This may also be caused by an engine running rich which is a number of possibilities.
