the ICV replacement got rid of the core issue. I also did the a cooling system refresh after that to get rid of my intermittent coolant thermostate sensor code, and now now codes are getting thrown, so yeah.. it seems to be fixed, and in my case, the ICV was the culprit. My old unit was pretty dirty (having looked at it a bit, not necessarily here/there, but I can imagine it being involved, around 109k miles on the clock fyi.
My exhaust donuts were fine, not releated at all in my case.
Sadly, in the final steps, my 1.5 year old repaired footwell module crapped out. So I went for a new retail unit this time (le sigh, this car, I swear...)
