I threw a code today. First time the SES light has eve come on.

I went up to Autozone to have the code read

It was something like:

P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2) (or very close to this..I washed the damn slip in the laundry tongiht and its not readable now. I know the code deals with the O2 sensor that is supposed to be AFTER the cat. converter.

I have a Mac pro-chamber with Dallas Mustang MIL eliminators. The eliminators are around 4.5 years old. I havent had a chance to get under the car tonight..but I am thinking that either the MIL came unplugged..or is dead.

What's your opinion?

Yea.. the code is the passenger side catalyst monitor (the one after the cat.)

I would definately suspect the MIL eliminator wiring if you haven't messed with anything else. If you don't see anything immediately obvious, I would unplug the connectors if they are plug in style, and spray some QD electrical contact cleaner in to there, and see if by chance corrosion or something got in there. Also, I would check the tightness of the rear o2 sensor on the passenger side to verify that it hasn't backed out or anything.
