Wackiness on Bank 1
13 Silverado 2500
We replaced the Bank 1 sensor 1 o2 sensor because of codes relating to it. That seemed to make it run better, but just the O2 sensor didnt cure the problem. The problem didnt show up for me until the last time I drove it. Before that 50 miles of different roads didnt make it come up.
For some reason Bank 1 seems to be quitting. I didnt have the scanner on it when it started running rough, so I couldnt monitor the problem. Of course it happens to the driver all the time after we give it back!
P0300 for misfire always comes back along with low voltage for both bank 1 O2 sensors. Both sensors have been replaced. Right now I'm guessing an intermittent wiring/ground problem so I'm searching for the wiring diagram.
Anyone else ever encounter a problem like this? Maybe you can post a fix before I find it on paper.
Thanks for looking.
