Well I was at work and I did not have any deliveries so I finally got around to pulling the ecu code. Since I turn my car on and off so much it goes away pretty quick. It comes back on if the car has been sitting idle for more than 5 minutes. The code for 0115, lean. My car has 76000 so I am thinking maybe O2 sensor. Should I try something else before I move to the o2 sensor?

Oh, I should have noticed that my car is running lean because my A/F meter was not jumping all over the place in the same pattern as before.:)
