The lower O-ring on the injector seals the injector to the inlet manifold. A leak overthere, would let "false", uncontrolled air, enter the manifold. But this would be a constant leak and should not cause any stalling. You can try and spray some water on each injector base while running the engine and see if there is any rpm change, which could indicate a leak.
Still strange though that the rpm go down when shifting into Park, because you release the load from the engine, which would give the expectation of an rpm increase and not decrease.
Also still strange that your TPS is not stable, on mine i never saw it changing even a bit, when i donīt touch the accelerator.
I would disconnect and clean the connectors on the PCM, just to rule out any resistance problem overthere due to dirt/moisture/corrosion.

Could the ground wire not being connected to the top of coil pack #7 cause my issue?

Re: Almost stalling when shifted into park

Not sure if it would cause the problem you have now, but if its not connected, I would do so. This ground wire is not there for nothing. Many times this wire is forgotten, after changing the spark plugs.

I may have found the problem. I think my battery terminals are bad. When I put my multi meter leads on them I cant get a good reading unless I scrape them a little bit. And the voltage drops when I have a bunch of things on and I rev it in park. The rpms also drop too.

Did you go through the sensor re-learn process? Using the accelerator to force the motor to stay running in park, then again in drive? I had to do this when I replaced my IAC, Crank position sensor, and cam position sensor, and any time I disconnect the battery.

Working through this myself. Changed the governor switch and it's all fine now. I was hoping I wasn't going to have to dig into stuff with the pcm.
