the dme switches between open and closed loop based on engine speed (rpm) engine temp, and throttle position - perhaps on of these sensors is wonky (hmmm, throttle position comes up again ...).

Radium King I can’t thank you enough for your help! Here’s answers to your questions
-I forgot to mention resetting the dme. I tried this multiple times and finally letting it reset over night did the trick and allowed the car to run.
-The dme was switching back and forth at open closed loop at idle.
-I replaced the engine temp sensor during the original trouble shooting
-I haven’t replaced the TPS, could it cause a repeatable rpm related problem?
-The only codes were rear O2 sensors and random misfires(before dme reset)
