Can a leaking exhaust manifold cause a catalytic converter to fail?
Another common problem related to catalytic converter failure is a leaking exhaust manifold. In order to prevent this from happening, and avoid some costly repairs, Park Muffler has put together a quick guide to leaky exhaust manifolds and catalytic converter failure.
What happens when the catalytic converter is clogged?
A clogged catalytic converter prevents your engine from breathing properly. As a result your car may experience a lack of acceleration and overall performance. You may also notice the fuel economy drop. Excessive exhaust back pressure can choke the engine, causing it to stall.
Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
When do you need a catalytic converter cleaner?
There is a caveat for this method. It only works when the catalytic converter is not seriously clogged. You will need a catalytic converter cleaner. This method is also great for cleaning your exhaust and fuel systems as well as your oxygen sensors. Here’s how to go about it: Get a catalytic converter that works well with your car.

What should the pressure reading be on a bad catalytic converter?
When increasing engine speed to about 2500 rpm, you should get a pressure reading between 1 and 3 psi. Your mileage may vary, depending on your particular model. However, a reading of around 8 psi or higher means you are dealing with a clogged converter, exhaust pipe, or muffler.
