I have a 97 Lexus ES300 that I bought for my son. The check engine light has always randomly come on, however, the trac off light now comes on and stays on. Both lights are now on most all of the time. The car, however, seems to run perfectly fine. Any ideas?

Try checking wiring of engine lights or let it be checked by any garage they will scan it in about 20 bucks, otherwise take it to your dealer. Good luck!
