I recently Purchased a 2006 Dodge Charger RT as a mechanic special. I Scanned the Codes when I bought is and the only codes showing were for all 4 O2 sensor Heater circuit Low (P0051,37,31 and 57) the Car drives fine most of the time, but at random times no matter if it’s in park or drive it idles very poorly, shakes the whole car violently, and after 30 seconds of doing that stalls out/ dies. It had also done this while driving where it just shuts off randomly, while in motion or sometimes at a light. I’ve pulled the PCM and it says it was a Remanufactured unit and it was replaced it 2022. Cleaned all the connections with electrical cleaner and reinstalled (yes I did the proper procedure for R and I) I’ve tried resetting the PCM by pulling the fuses mentioned in another forum, didn’t fix the issue. Just wondering if I should replace the PCM again (maybe a bad one was used) or if it’s not the problem at all and should look into other solutions. I’m a mechanic so I have no issues doing this all myself but I want a second input before I just start throwing money and parts at it. Thank you!

 

You need to see why you are getting codes for the O2 sensors. They have a rather profound affect on how the engine runs...... Given that it is whining about ALL of them...... I would expect a blown fuse, or bad relay.

 

Do you have any codes for a misfire? I was thinking possibly the catalytic converter.

 

My charger is doing this exact same thing and same codes. Did you ever figure out what was causing this
