Engine runs fine after ECU reset, poorly shorty after

[Zachccccc]

This all started when I pulled off the highway and noticed the brakes surging. The cause being the engine revving to what can be guessed as 900-1300 RPM. Pulled into my apartment, and stopped the car put it in Park. Noticed that the car revved high still, turned the engine off and restarted it. Upon restart it idled pretty rough, but was idling low.
Went to advanced auto and got them to run codes, threw a
P0301, 302, 303, 304. Misfire on all 4 cylinders ! In addition to a a VVT code that got thrown.
So I opted to replace my plugs in hopes that was the issue. Replaced the plugs, with the battery disconnected to do an ECU reset. Started up and everything seemed to run normal. No rough idle no random revving.
Drove 3.2 miles to get food for my roommate who helped me replace the plugs, stopped the car at the Taco Bell car ran fine no revving or rough idle. Started fine as well drove back to my apartment 3.4 miles.
Ran fine until I got into my parking lot and the revving came back in addition to the rough idle.

So it's not a mechanical issue as it ran fine on the reset ECU, it's a sensor issue making the ECU 'learn' improperly.
What do you all think ? I'm leaning toward MAF sensor but I dunno the VVT code seems to make me think it could be the VVT solenoid ? But would a VVT solenoid effect the learning and make me misfire across all 4?
