What is your question?
I have a 04 dodge ram 5.7 hemi. The check engine light is on. I took to the parts store and had them read the codes. It came back as bad o2 and bad catalyst system. I then took to my local shop and had them do tests. They said bank 1 upstream o2 sensor is not sweeping. I've looked around and think my pcm needs reflashed? Could that fix my issue? The truck has no power check engine light is on and if i give it hard acceleration it won't shift. Thanks for any help.

My girl friend had a car that when the ck engine light came on the car would dog out an use gas she would shut it off an start it again then it would be fine for awhile she said it was the coil packs going out
