2006 Durango 5.7 Hemi rough idle/etc issue Sign In

I have a somewhat common issue 06 Durango 5.7 hemi that has the following codes. It all started while driving and it died all of sudden with a flashing ETC light. It now will start but the rpm jump up and down from 700-1500rpm in any gear with little throttle response. The engine will not get over 1500 rpms driving but it seems the pedal is responding to pushing it but no response. I took it to the dealer and they were confused and said it appeared to be a PCM issue and wanted 2k to fix it. I have replaced the PCM computer from a mopar programmer with vin/mileage and a used throttle body with the same response thinking it was the TPS that was attached to it. I am at a loss and don't want to replace the pedal positioning sensor that's 200$ before dropping another 200$ at another dealer to troubleshoot.
Please help the codes are as follows.
P0520 Oil pressure switch (replaced in July 2017 but the oil pressure light is back on now)
P0335 Crankshaft position sensor (Replaced last month but the code is back on again)
PP2111 Throttle actuator control system (Replaced throttle body same code)
P0642 sensor reference voltage A
P2122 throttle pedal position sensor/switch D
In a similar thread a Dodge mech said to replace the oil pressure switch again since they are on the same harness and can short each other out. does this sound possible and can either of these sensors cause the rough idle and lack of throttle response?
Any help is greatly appreciated.
