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.

So limited mostly to cyl 1 no matter what coil or plug used.
If you could hook a Digital multi meter into the wiring for cyl 1 make it misfire and see if the signal from the DME/ECU is at fault.
Or use a spark test thing that goes between the plug and the coil.
Try to eliminate the DME/ECU and wiring as an issue. (electrical).
That would eliminate the Alternator as well if the issue is not electrical.
