My 2013 Ram 1500 decided to go haywire. It gave me a persistent misfire code on #8. After doing everything possible to rectify the problem, I decided to get a refurbished PCM. I followed the procedure to the letter to put it in; and she fired right up. The #8 misfire is gone, but now I have a persistent high voltage on one of my O2 sensors. Again, I changed it, to no avail. I'm assuming this computer is faulty too. What did I do wrong???

Maybe grab a multimeter, disconnect the wiring connector, and measure the voltage on that O2 sensor signal wire (key ON) ((harness side)).
