Finally just happened to hear a slight buzzing from the the throttle body when checking fuel pressure for the 10th time, gave the ICV a couple taps, buzzing stopped, car cranked and ran like normal. Like nothing had been wrong. I put a bosch unit in, no issues since. I had never heard or read of one failing, so I looked over it multiple times. Just throwing that out there.

Funny you should say that. Same exact thing happened to me. I actually took the whole unit apart and used some QD cleaner on it.
But when I was having the issue, I would still get some sputtering, and sometimes it would start but run really rough. Had a few other weird symptoms before that as well. All cleared up with a good clean though!
