My 2000 dakota has started acting very strange. it started with a P0171 code. It now has codes that say all of the O2 sensors are bad, but when tested individually they are good. I wonder if it is the PCM.
If I replace the PCM, does the dealer or someone have to code the VIN and milage?
Thanks,
Jim Buckingham
