P0156 is a circuit malfunction code for the driver's side rear O2 sensor, it is generally associated with a wiring problem.

The MIL eliminator could have a bad connector or wiring, or the MIL eliminator itself may be defective. It is possible the O2 sesnor is bad--more about MIL eliminators and how they work here.

The only way to test is to get under there and monitor the sensor's output, both before and after the eliminator...

Yea my friend is going to check the mil for me this weekend and see if the wiring went bad or not. Hopefully it is cause I don't feel like buying a tuner right now for the little mods I have done to my car.
