    Thanks! Got your email. I'll hook up the multimeter and see what ohms I get out of the wires

    Check to ensure that there is continuity across the heater circuit too with the sensor plugged in.

    Ok so I finally Ohm'd the wires. Each wire to the PCM read 0.2 and the ground was 0.0 You guys have any other ideas what the issue could be?

    To make sure I understand - you disconnected the harness at each O2 sender and the PCM and then individually tested each wire?

    What MAF did you install... was it the GM replacement with the plastic housing and adapter harness?

    I am emailing you the complete P0131 diagnostic (3 pages).

    its possible when you melted the first harness it effected the computer . i had a computer go bad when the wires for the o2 got melted on the exhaust .

    Is there a way to check the pcm to see if it's bad?

    i ended up replacing it and that fixed it , dont know if frost or one of the tuners could test it or tell you how to test it .

    What's the process I need to do in order to get the correct computer. Frost sells them along with the tune don't he? I had mine tuned by him a couple years ago

    I would beg, borrow or steal a scanner and watch the live sensor data from your O2 senders before replacing the PCM. Throwing parts at a problem is really a method of last resort. Reading into it more, it could be as simple as a bad tank of gas, low fuel pressure, an intermittent ground or a vacuum leak.

    I have a scanner that can do that. Just don't know what I'm looking at lol. It's not fuel issue nor a vacuum. Gauges both and they are spot on.

    did you check for proper ground and voltage at the sensor , there should be 12v for the heater , 5 v from the computer to the sensor and a ground , the last wire feeds the computer voltage back . not sure what color does which . i believe you can test for voltage with key on engine off . the wire feeding back to computer the voltage should vary while engine is running . you can check with a multimeter if you dont have a scanner .

    On your scanner, you want to watch the live O2 sender data - it should be displayed in mV (millivolts). The Bank 1 - Sensor 1 and Bank 2 - Sensor 1 data should rapidly cycle up and down from maybe 150 mV to 850 mv once in closed loop. They should change quickly and not appear at all sluggish, nor should they be hanging out in a specific range for any period of time. The correct air/fuel ratio, what we call stoichiometric, is around 14.68:1 (a little fatter when 10% ethanol is factored into the equation) and the O2 senders are calibrated so that this is equivalent to 450 mV. However, fueling is a moving target and that is why you should see the data quickly cycling up and down. The stock and replacement O2 senders are "narrowband" and the data stream is useless for gauge purposes, that is why we run "widebands" in our cars when an air/fuel gauge is installed.

    If you want, shoot a vid of what your display shows and post it up.

    If you have a lazy sensor it'll usually be pretty apparent, especially when the other one is working as it should.
