@ddg599 Seems like you have some substantial problems. IMHO with a car throwing that many codes that sat for years, it's best to start off by 'baselining' the engine. Or else you're going to play whack-a-mole with problems. I would get the injectors cleaned and flow matched, make sure all your plugs are good or replace them, test the ignition wires, clean the MAF, smoke test the intake and exhaust, visually inspect the cats (the matrix tends to break loose), and test the o2 sensors for resistance if not replace them.

Most of these suggestions have been done by me at this point to indeed get a baseline. The cats are not broken or damaged to sight, new Tubi headers as of now, Need to test O2 sensors, cleaned MAF, ignition wires fine, plugs new, will pull injectors soon but not right now, but that is a valid point for not a lot invested as I think #7 might be damaged beyond repair. All great points.
