Any ideas what to do next? So frustrating!

At this point I would get a new MAF sensor, yours is no longer good even after you cleaned it.
Put back an oem filter, and use an obd2 scanner to reset it, should be fine after that.
If the maf is bad, it doesnt matter what filter u use it will affect the fuel/air mix and cause the car to run rough.
I don't believe its your your throttle body controller as I just went thru this myself and a new MAF fixed it.
The MAF sensor comes in 2 types, with and without E-Gas/E-Acceleration, need to find out which your car uses.
Air Mass Sensors are also known as the: Air Flow Meter, Air Flow Sensor, Air Mass Meter, MAF, Mass Air Sensor, and Mass Flow Meter.
The Air Mass Sensor measures the air mass that flows through the air filter to the engine.
This information is then sent to the control unit in order to specify the fuel injection rate.
Common symptoms for an Air Mass Sensor that needs replacing include:
- Erratic Engine Operation
- Reduced Performance
- Engine Stalling or Cutout
- Increased Fuel Consumption
* Please remember to reset the ECU after replacing the MAF or the car may continue working as if the old one was still installed. * (by unplugging the battery or reset tool).
