Thanks for all the info!!
Some more follow up answers/questions.
It has 130k miles. It has severely overheated, but after I was able to get more coolant in it, it drove fine. No serious oil leaks to speak of.
It will do the chugging popping at any temp, starts as soon as start it and take off. Idle is kinda rough, it won't do the backfire pops but it was tripping the cel. Since last battery pull I drove the car a block or two and experienced all symptoms mentioned but the cel did not come back on yet...
And by 3 misfires. I am saying that 3 cylinders were misfiring, all but cylinder 2. And has since moved to only cylinder 1&4.
Just pulled the plug on #1 and it has some char marks from I'm assuming some kind of electrical arc on the porcelain part where the rubber connects to the plug. The other 3 plugs appeared to be in ok shape. No bad residue buildup.
I will be replacing all the gaskets to fix the oil on the plugs issue. But I'm assuming I have more going on then that. And that the oil is not the cause of the most severe issues...
As far as the type of plugs. I got the double platinum ones, seemed like the best that auto zone had. Are those ok or do I need to get something really specific? Not sure what NGK means? I believe the wires are the original.
Is the mentioned "coil pack" something different then the part I'm calling the "ignition coil". The part I replaced was the little box on top of the engine that the four sparkplug wires plug into.
Again, THANKS!!
