I'm not sure if I should put this in here or in the troubleshooting section but I'll just post it and it can be moved if necessary
I've had the MIL eliminators from MSDS for a few years now and I've never really needed them on the Contour (always had tunes that just turned the rear O2 sensors off) But with my stock tune I'd always get a check engine light. I swapped them over to my cougar now and I am still getting a check engine light. I got a P0161 Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2. So maybe the MIL on that sensor is no good? Would there be an easy way to test this? Since the check engine light is on anyhow I'll probably just pull it out and take a look at it. I guess I could cut it open and make sure all the wires are still intact? Or would it be easier to just test and see if I had the right resistance going through it? Maybe this is something completely unrelated but I find it hard to believe I had bad O2 sensors on both cars after removing precats :laugh:
Thanks for any ideas in advance.
