Had my SES light come on while waiting in traffic yesterday. Checked the code when I got home and returned P104 lean condition detected. Haven't been able to locate any vacuum leaks; code is cleared and the car has been driven 50 miles more without the SES light coming back on, but was wondering if anyone else has had the same prob and found a reason other than vacuum leaks.
All the O2 sensors are original; about 83,000 miles on the motor.
