Symptoms include rough idling and stalling. This noise is produced when the engine spins its parts to create the required driving power. I had a similar problem with my 06 Saturn Ion Redline (2.0 supercharged) - I found that the ZZP stainless exhaust parts were less expensive than factory and fully EPA compliant.

When the ECU notices that the catalytic converters performance is below the threshold, the P0430 code is set.

Though these may appear identical to the oxygen sensor (O2) pre-converter.

Part of your vehicles exhaust system, the catalytic converter takes carbon monoxide, a natural byproduct of any gas-burning engine, and switches it to carbon dioxide before it is released in the engines exhaust. Carl Stolz - Technical Sales Manager, DEC.

YMMV.

The gaskets are also installed between the engine and exhaust manifold. There are various exhaust tapes, and their methods of application can be different. It could also have caused leaks elsewhere in the

It is important to remember that if the "Check Engine Light" illuminates and you read a code of PO420, 421, 430 or 431 this does not necessarily mean the Catalytic Converter is bad!
