Well got an OBD II scanner and found 2 codes. P0507 - Idle air control systems rmps higher than expected. And P0120 - Throttle/Pedal position sensor A circuit.

Took off the intake and looks as if the IAT sensor is in place and clipped fine on the y pipe. Tried to start again and same issue, right upon startup it goes to 2500-3000 rpms and stays there. Dont see any lines off.

I'm stuck.

EDIT: And there is a weird buzzing sound coming from the Throttle body it sounds like. I tried unplugging the throttle body connect and reconnecting it and same same. Loud buzzing,
