2004 Toyota Camry 4 cyl Front Wheel Drive Automatic 50200 miles
My '04 Camry runs very well. I have followed all of the maintenance criteria with my owners manual. Yesterday the " CHECK ENGINE" light came on. I checked the gas cap. It was secure. I even unscrewed it and re-tightned it. I checked the oil and tranny fluid; all was well. What do you think it could possibly be?
