I recently did the new pistons install on my 2002 tj 4.0. Im not sure if I plugged the o2 sensors into the right plugs. Its showing a code for an o2 sensor and it does seem to be running a little rough like it would for something like an o2 sensor. Does anyone have any info on which wires go where in a way they can explain or show pictures so I can narrow it down to that or if I need to replace o2 sensors.
