Had the same problem and lived with it for 3 years; finally check engine light didn't turn off with new gas cap and needed to replace catalytic converter. Unrelated, have put in two water pumps one at 90M miles and this one at 148M miles. Still love my car and parts do fail. This has been a very reliable auto. Now I've learned I should have had my brake fluid flushed with the brake jobs...that's next on the maintenance schedule.
