Rough idle as of today

[Kittenpunch]

I had the car out for a spin last night and it was totally fine. However, I just tried to take it out and noticed the idle was pretty iffy, and the car had a significant lack of power, so I spun it around and parked it as to not mess anything up. It's been raining pretty heavily so I don't know if water got into the intake or anything like that, but it's pretty rough. I'm thinking spark plugs or wires, because I'm not sure when those were last changed. Also the engine itself is shaking pretty bad so maybe the timing is off? I'm not too familiar with these bad boys as I'm a new owner. Any insight would be appreciated, though.
