Hi All, My 2021 Dodge Ram 1500 5.9 has had a problem where when it warms up it backfires and hesitates on acceleration with little power. When it is cold til it gets up to temperature it runs pretty good. Also, it often doesn’t idle and there is a tick tick under the dash at the same time. I have checked codes and get a P0132 and P0136, have newer O2 sensors and many other sensors. I found the 02 sensor fuse was corroded. I cleaned it up and it worked for awhile, but the problem comes back. By the way my truck has 268,000 miles (I have owned it since new). I had to replace the PCM a while back cause of a loose pin. I need my truck yet for awhile. HELP! Thank you. George

 

What brand O2 sensors did you install? If you got Bosch sensors, those need to go. NTK or Denso only please. These trucks don't like any of the others.
