I just replaced both of the O2 sensors on my '96 due to a CEL code for Bank 1 O2 Sensor Lean Condition and Bank 1 O2 Sensor Heating Circuit Open. I was getting about 15 MPG with the old sensors. I've run 2 tanks through the XJ after changing the sensors, and I'm now getting 11 MPG. After the first 11 MPG tank I took the XJ in and had it aligned and had the tires rebalanced, but it didn't make any noticeable difference. I used the Bosch O2 sensors listed on Bosch's website for a '96 XJ, the OEM style, not the "Universal" type. Any ideas? With $3.65 gas this new low mileage is killing me.
