Something is ****ed. There’s no way your map should be 65-70 idling. Then it hits90?? Your map sensor calibration is jacked or its bad. Maybe bad grounding i dont know. Something doesnt seem right

Little lower, little cooler, bigger sounds.
Old engine had better idle vacuum, but didn't change this.
At that same time that the vacuum is heading to 90, the IAC is cranking open to 50 or better. So the vacuum WOULD drop.
As was mentioned above, there's definitely a cause and effect going on, and I think it's going to take some very fine line looking at times in a data log to see which thing is happening first.
I was starting to do that with the logs I took last year when my plugged in laptop started getting pissy about a dead battery.
So I put it away for now and looked up a new battery that I have to order today.
