It would seem to me that disconnecting that should have caused
some kind of reaction, the fact that it didn't makes me think something's amiss with it.
"From what I've researched about a failed ETA is that they either work or they don't. (There isn't an "in between" where they'll cause slight problems)"
When the insulation on all those wires inside those things go bad, they sometimes cause problems, but sometimes they work fine, just like when the main harnesses go bad, stuff works sometimes, sometimes it doesn't. I would think this would be less of an issue on a non-ASR car though. Does your car have ASR?
You would have been better served if you kept this all on one thread.
