you can try to clean the mass air flow sensor with mass air flow sensor cleaner. you can also try cleaning the throttle body. and a intake flush would also help since you said the car had carbon build up. Also you can check for intake leaks

 

Possible causes
- Faulty Mass Air Flow (MAF) sensor
- Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrcial connection
- Manifold Absolute Pressure (MAP) poor electrcial connection
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly
- Faulty Throttle Position (TP) sensor
