No, that code is for the evaporative emissions control system in the fuel tank. It has nothing to do with the catalytic converter.

If a 2001 Volkswagen Jetta's catalytic converter rattles and falls apart inside itself would that be covered under the voluntary VW factory extened emissions warranty even if you bought the car used?

AnswerYes, even used. See the EPA link below and show it to the VW dealer. Voluntary warranty extension from 8 years/80,000 (req. by EPA) to 10 years/120K miles. But, if the catalytic converter has ANY visible damage the factory will refuse to honor the warranty. Since it can't be determined if the converter or the damage is the root problem. So before you spend the money to get the technician to determine if it is covered check the converter yourself.

What can you do if your 2003 Chevy Trailblazer is running rough and sputtering and gives you a flashing service engine soon light when accelerating and a steady light coasting?

The FLASHING light indicates a do not drive situation. This is usually indicative of a misfire. The code will show up and tell you with the use of a code reader. The code will tell you which plug. Most times it is a bad plug or coil pack. The rich condition created by the misfire will melt your catalytic converter if you continue to drive the vehicle. This is why the light flashes.
