Default Misfire symptoms, no CEL. OBD1 2JZGE

Trying to see if anyone else has experienced something like the problem I'm having..

Purchased the car, drove it and it was fine.
Left it parked for ~4 days while I was working on cleaning her up and started her up. Idles good for about 2 minutes, then starts misfiring/idle dips. Not sure if oil or gas, but there is smoke during the misfiring episode. About 5 minutes later and when the car is completely hot (i assume), it doesn't misfire/hesistate at idle but does it randomly.

I can't see the rings going bad so suddenly, but the smoke (assuming it's oil) can mean bad rings, PCV or EGR?

What color is the smoke and how thick is it.

It's dark, I can't tell whether blue or black. Not too thick, it subsides after a good revving.

Seafoamed the engine through the brake booster line. Used about a half can of it and it smoked for a good while, so I will see how she idles tonight. Ran her around the block and she was running fine, but you never know. lol
