I did check the fuse it was fine.... just cant see how it is giveing me codes p1131 bank 1 lean and p1132 bank 1 rich how can it be lean and rich at the same time,,,,

Edit--I was wrong. Those are indeed codes for the bank one sensor only.

If it was me, I would swap the bank one and bank 2 sensors with each other, and see if the problem moves to bank 2. If so, I bet the sensor is bad.

Tryed swaping the bank 1 and bank 2 sensors with each other today going to drive it and see if that works... just cant see how it can give me a lean code and a rich code at the same time,,,,,,,,,

It could if the sensor itself is bad. New isn't always good, that is why they have warranties.
