Re: Not Running Right...
Do we have a traction control light on our WJ´s? Or do you have a 2004 WK?
I had a similar problem some time ago, it was only always there and not once in a while. Driving around town all ok, but when accelerating on the highway there was just lack of power. Passing some other car was just a risky thing. After changing my fuel filter/pressure regulator the problem was solved. Problem could also be with the fuel pump or even with the TPS sensor. If you have the possibility to measure the pressure at the fuel rail, you will know more.
