check engine light 520i


So the check engine light has been turned on a few hours after i bought the car.
It didn't seem to serious, and it went of later.

Now the car started stuttering today, especially when giving gas, being in stationary and around 40-60 KM/H

What i've found on google is that the air intake probadly doesnt go in properly.
Also, i've put 95 unleaded in the tank as fuel.

What i want to know is where i should look for problems with the air intake.

I haven't gotten my error codes read yet.
