I have done that before and it's the same results.

yes, it does seem like it is heat related.

My gut tells me there is a single thing that is causing all of these things to happen, but, each individual item could be caused by multiple things too. I just can't seem to narrow down what the 1 or 2 things are that is causing this.

It could be a couple things and when combined are causing misfires, low vacuum, oil light coming on when coming to a stop, hard downshift from 3rd to 2nd. It's just the only thing I can think of that could cause all of these things is an air leak or an AOS but I dont have any other symptoms of a bad AOS or a bad cat. it misfires at idle and around 2800. The misfires are a symptom of the issue, dont think they are the cause of the issue.
