Bogs Down Around 3600rpm

No probibly not... Not unless there was some bizarre event and the laws of physics were negelcted, nothing I can't think of would do that over night. The car would have had to be sitting or the secondarys never were working and I assume that they were.

It backfires when you downshift, that means, the ACV (air control valve) valve and/or the AAV (anti after burn valve) on top of ACV don't function as they should.
check the lines that go to the ACV. Yo ucan check my web page (in sig) for ACV under emissions->secondary air
Since it was working fine before, you must have crossed some vacuum lines.
now, if you ditched the air pump and ACV long time ago, this above is just BS
