Lightbulb O2 senor fooler??

Im not sure what there called, but does any one know or have experience with the devises you plug into ur o2 sensor and it mimics what the o2 sensor would being telling the computer. Im looking into one for my rear one on a 98 xj . But idk much about them or if there a good idea or bad. opinions welcome

are you talking about using the spark plug non-foulers as O2 spacers?

Use a diode. My buddy gutted his cats and used a diode on the wire of the 02 sensor

My 02 circuit was giving me trouble on my 1998XJ.

I found a post on some forum, may have been this one.

There is a 15 amp "unmarked" fuse in the box near the battery.

Mine was the bank of the smallest fuses. It was on the back row, second from the passenger side. Popped a new one in & problem is fixed. This was over a week ago & still no check engine light.

as for the spark plug non fouler, you use 2 of them, drill out one of them with a 1/2 drill bit, thread that one onto the oxygen sensor, then thread the non-modified one onto the modified one. It worked on my buds 01 Civic. He had a p0420 Cat efficiency below threshold. O.E. cats where on back order and he waited til the last minute diagnose it. He threw the non foulers in there to pass emissions and til the new cat showed up.
