Tried to put my XJ against a Camaro ZL1. Dropped the driveshaft, and in the process of repairing it, the shop replaced an O2 sensor that was ripped out a while back, and now my fuel mileage has gone from bad to worse. I was getting 14 on the highway, now I'm getting about 10. Help?????

yeah man, details details! Year, motor, rear end, lift if any. What have you checked? Fluids, air filter, tires, plugs etc...Originally Posted by fireman1600

Why would you pit an SUV against a car known for speed in the first place? Originally Posted by s346k

Different vehicles were designed for different uses. Funny thing is, you don't see camaros trying to kill it offroad...
Stop trying to be fast n furious. You want to race? Go to the track. With an appropriate ride. You got what you deserved.
Sorry if that's harsh, but grow up man.

Is this for your 1994 XJ, 4.0 Liter?
If so, you need an NTK 23023 O2S.
If a Bosch O2S was installed, yard it out and install an NTK O2S (above part number).
If this isn't for a 1994, you need to specify what year you have.
