Wideband O2 sensor ("shoulda bought this years ago")

Did the same for mine, went with an Innovate and found out I was a little lean with a T/Q. richened it up, better idle and cruise throttle response. power across the board went up and my mileage went up to 15 from 13. Next is switching to 2.94 from 3.55 gear set to see if it gets a little better mpg.
