Oxygen Sensor Simulator
I've got a custom exhuast on my 97 and tore out the cat. I've got the check engine light on, but the 3.9 definatley seems to be running too rich. Are there any oxygen sensor simulators that do not require actually screwing in the sensor cause I didn't put a hole in my pipe for it and dont feel like doing it unless i have too. Thanks

mine doesnt actually screw in but you have to wire it into the wires on your preexisting o2 sensor. the heating element cant be by passed on your o2. however your secondary o2 sensor has nothing to do with running rich. it just tells your computer if your cat is bad or not

Can't say for sure, I didn't really notice anything. I wouldn't think so cause as mentioned it basicallyjust tells the computer the cat is good and eliminates the cel. Getting rid of the cat or going to a hi-flow one might help performance, but I don't think the OSS alone will.

RE: Oxygen Sensor Simulator
i took the cat off mine and the engine lite come on too i bought a special pipe that angles the sensor pointing twords the back of the truck adn the sensor is sunken back a lil bit and the check engine lite is off now i think as long as the sensor isnt in the line of the exhaust it should be fine mine has 175,000 on it soo i need it tuned(burns rich too)
