I've got a buddy who I'm helping engineer a 5.0L Mercury Moutaineer/automatic tranny swap into a 940 Volvo sedan. This model has O2 sensors upstream and downstream of the each cat - 4 in total. I believe this is similar to the set up you guys have on the mod motors.
What are the implications of removing the cats with this set up? Check engine lights? Drivability issues? And, the MIL extenders (is that the right term?), how do they work? I assume it alters the output signal of the rear most O2 sensor to fool the computer into thinking that the cat is still there. Do they plug in between the sensor plug and the harness plug? Who makes them - contact info would be great. Need to find out if they have an application for the Explorer/Mountaineer application. Thanks in advance for any help.
