Moving my O2 sensor?? Help Please
So taking advice from many Wheelers on here, I recently sold my YJ 2.5l and got me a TJ with the 4.0. Now a week later I am releazing it is sluggish and seems less powerful than the 4 cyl? No engine light on, but you can hear the rattle from the cat breaking up inside. I took it to a local muffler shop just to make sure this was the problem and they have confirmed it. However, they price quoted me for $600 for new cat muffler installed. This is rediculous and I am not paying it. My question is has anyone ever gutted there cat and straight piped it? My 1997 has a sensor on the cat so do u think if i did this i would be able to move the sensor right behind where the cat sits on the pipe itself? Would this throw codes? Please help if u have done this or have any advice.
