Hello!
To make this quick, I have a p0300 and p0052 code. I have changed my spark plugs, ignition coils, o2 sensors (even swapped bank 2 s1 with known good sensor), Air filter, and now I'm just lost and feeling like my heater circuit wiring from bank 2 sensor 1 may be broken or corroded. Does anyone have a wiring diagram for the O2 sensors that goes to the PCM and maybe some troubleshooting tips? Wiring diagrams for the entire PCM would be greatly appreciated as well.

Also, Originally I had no codes and just changed all of my front end control arms. Brought it out of the shop a week later (military base auto shops have horrible hours) and then the code popped for camshaft sensor and all O2 sensors bad. I changed the Camshaft sensor on bank 2 (driver side) and the O2 sensors. Everything cleared except for Bank 2 S1 heater circuit high. I changed everything listed above but still get random misfires. I'm almost confident my fuel system is good. My battery is a bit lower than the average read but still works fine. Hoping someone who has had this issue can tell me their solution. No way I'm the only one right?

Currently I have the PCM off and a Multimeter ready but of course I work today through Friday so I'm limited on time. That and I can't afford to keep taking it to a shop to diag for the same suggestions. My nearest Dodge dealership is 20 miles away and I do not want to drive a misfiring car 20 miles and back. It only misfires noticeably at low RPMs when I'm going like 25 and below. I'm almost sure my gasket on my head is fine. Car is not overheating and no weird noises besides the fact I need an alignment for my control arms because when I hit a steep bump, I hear it click. That's not my main priority because I need the car to run properly first. Thank you all so much for whoever helps! I really am getting fried working on this.
