Dsc problem

Got in the car and turned on and dsc light was on. Had no power etc at first. Turned car off and restarted....dsc light was off but still have no power...what I mean by no power is like when dsc is on all the time. Can anyone help me on where to look for problem or what is wrong? Could HPF kit have anything to do with it. Thanks

Most often it is the one on the throttle bodies. Super easy to change out, about $80.00.

Thanks for help. I plugged in my OBD ll reader and P0121 code or BMW 121 came up and it showed TPS/ pedal position sensor so it must be the sensor at the pedal!!
