You may need to load test the wiring for the throttle body to find the resistance that'* causing your problem.
Before going after that do the grounds real good first.

Thanks for the help guys! Still no issues since I reset the codes but I’m sure it’* just a matter of time. Not sure how to load test the wiring but I’ll let you know what I find out.

Did you clean the grounds?
Load testing will cause small hard to find problems in a circuit to rear their head. You will see why the circuit needs a good load that power probes, LED'* or meters do not apply. We find a 4 amp bulb does great.

So, just apply power (12v) thru the wire to a 4 amp bulb and complete the circuit with a ground?

Yes. Ours is a home made test light using a 4 amp bulb. If the bulb is flickering or dim you know there'* a resistance in that line somewhere. A good wiring diagram is needed. Any splice or connection of any kind needs to be examined.

Thanks for all the help. I didn’t find anything notable while load testing and the ground checks out good. Unfortunately, I am running out of time to spend on this. I have shoulder surgery scheduled next week.

The codes have not resurfaced yet. I really think it is dirty contacts in the plug. I am going to try cleaning them up with contact cleaner and using a little dielectric grease then see what happens. If it rears its ugly head again, I will deal with it after recovery.

You all have been awesome! Thanks for the help.

Good luck with the surgery, and let us know if the issues come back!
