2004 Toyota Camry keeps dying while driving but it starts right back up. Replaced fuel pump and air filter but it's still doing it. Someone said it may be the catallytic converter? Does that sound right?

You may have problem with your cooling system. Follow these simple steps to try to rectify the problem:

1. Write down the code of your radio.
2. Allow the engine to cool down. Disconnect the battery negative terminal.
3. Locate the ECT-engine coolant temperature sensor. It is located to the right of the engine head-cover, by the metal hook. The number two sensor with black wire connector. You will see the large coolant hose connecting to its body. That's the ECT.
4. Depress and pull out the wire plug.
5. Use a deep socket with wrench to remove the sensor.
6. Replace the ECT, reconnect the plug wire and the battery negative terminal.
7. Crank up the car again and test drive.
