Do new catalytic converters smoke?

Does the catalytic converter affect the engine?

Reduced engine performance The catalytic converter is built into the vehicle’s exhaust system, and as a result, can affect the performance of the engine if it develops any problems. Both can negatively affect engine performance and can cause a reduction in power and acceleration as well as fuel economy.

What can happen if excess fuel enters the catalytic converter?

Too rich and the catalyst can melt down from fuel burning inside the converter. Too lean and the converter will not be able to serve its purpose changing hydrocarbons into safe elements. This may cause your vehicle to fail the emissions test during the annual State Vehicle Inspection.

How do you burn a new catalytic converter?

How to Break In a New Catalytic Converter. To start the break-in procedure, start the car after you’ve replaced the cat. Let the car idle in place without applying any gas.

How do you burn out a catalytic converter?

How to Burn Out a Catalytic Converter

1. Drive your car with a malfunctioning oxygen sensor. This can cause thermal failure, which means that excess raw fuels are making their way, in large quantities, to your catalytic converter.

How long does it take for a new catalytic converter to work?

Most converters start out at about 99 percent efficiency when new, and quickly taper off to about 95 percent efficiency after 4,000 miles or so of driving. As long as efficiency doesn’t drop off more than a few percentage points, the converter will do a good job of cleaning up the exhaust.

What causes a car to sputter after changing the catalytic converter?

The catalytic converter gets clogged if it is too old, and it can also come parts lose inside of it which will block the exhaust way. This will cause too high backpressure to your engine, which will cause the engine to start sputter. You can use a catalytic converter cleaner to try to clean the catalytic converter.
