Its for a vette, but a lot of the principals apply. Dont know what the correct voltages are though.

P0137 is second 02 sensor, so you are on the right path sophic, as Im sure you already know.

I don't know what to think anymore.

I already have a scan tool.

someone already tried changing the O2 on there car with the same problems and it still didn't work.
I don't feel like wasting money to find the same thing.

I'm convinced it is a computer problem.

First off, what mods do you have? Are you running a cat or not? It's hard to tell, because you said you put in a new cat, yet you also have an 02 cel fix installed?

Either way, if you put in the 02 cel fix, it sounds like you didn't get the wiring correct. Who's instructions did you use to install the 02 cel fix?

Look at the attached thumb, it might help.

White/black wire going toward ECU.
White wire going to O2.
It's installed correcty.

I am not completely familiar with that perticular code but from the sounds of it I am thinking the heater circuit is fried in the sensor and if that is the case then the mechanical nor electrical fix will take care of it. Take the sensor out and measure the resistance across the heater coil and compare to the spec.
