Are you insinuating that I am not intelligent?
As I said in the original post I pulled the engine codes and had the Following code:
P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2
I guess that I could have a short in the wire that corrected itself, since I have not openned the hood.
I know what gasoline is and how it works, I was wondering if they put some additive in that does not react well with the contour oxygen sensor.
When I bought the car the stealership replace the precats and the upper O2 sensors so I was hoping that they were still ok but maybe one front one is bad, and is working correctly right now.
