I have a 2002 Camry. V6. On the plastic engine cover it says V6 3000. It runs so well, it is impossible to tell if engine is running. But all of a sudden, it started dying at lights, or when ever you stop. In or out of gear. If you barley touch the gas pedal it idles well. I changed battery today, if that helps. Any thoughts on what to look for? Thank you. Mike Haley
