Car turns off

I haven't driven it unplugged just yet. I thought about cleaning it I even bought the thing but then when I took it off it looked so clean. Like it wasn't even really dirty. So, I returned the cleaner.

So, I unplugged it and the car revved up really high to like 3,000 then just shut off. Then I tried it again and it went up, started to rough idle because it below 600 and I turn it off because it started to vibrate hard.

And I disconnected the MAF while the car was on, and the engine shut off.

Funny story so I switched the MAF and forgot to plug it in so my cars turn on and shut off I said hmm. That's weird. So, then I tried it again and then it started idling alright. Not like the prior post. So, I cleared the dtc's and tried to start the engine again. It works pretty well. But the CEL still on, I'm like what. I click clear again and restart and it's still there. I then realized I didn't plug it in LMAO. Cleared it again and it's off. Now I'm about to go through my mils.

Waiting for the evap mil to clear. Everything else is cleared.

Went through the mil, and got a slight leak code for EVAP. I realized I didn't close the gas cap all the way. I'm just waiting a few days to check again.
