The vehicles check engine light came on. The catalytic converter failed per the diagnostic check at the dealership. The catalytic converter is covered by special 10 year or 120,000 mile warranty. The dealership says the good oxygen sensor is probably seized and it will break due to age when they replace the catalytic converter. They want us to pay $208 for a new oxygen sensor.

When attempting to leave a friends house my 2000 Chevy Camaro (3.8 L V6) would not stay running. After taking the car to the local mechanic it was discovered that the isc motor had "blown." Dealers and the manufacturer could not locate an isc motor right away. It turns out that this motor is actually part of the vehicles throttle body. The part that malfunctioned can only be purchased separately for the 5.8L V8, or so we are told, whereas the 3.8L engine must purchase the entire component. Currently, the mechanic is working on replacing the throttle body with a brand new, GM supplied part, since there are no aftermarket parts available for the 3.8L. The cost of towing and the part will total just short of $1100.

While driving in warm weather with the A/C on, the vehicle stalled when it came to a stop or when in heavy traffic. The vehicle could be restarted but would continue to stall until the vehicle was out of traffic. The diagnostic test could not determine the problem. The stalling occurred many times since the vehicle was purchased.
