my 2013 frs engine light keeps coming on and when i check it says its the MAS i had a after market intake and headers and had to take it back to stock because the mechanics said it was those things and now my light is still on and my traction control will come on once in a while, when it comes on when I m coming to a stop at around 10 mph it gives a little jerk. i read on another site it could be the air fuel sensor has anyone had problems with something similar.?
