i also have that problem I think its something in the throttle cable because if I put my foot under the pedal and lift up it will idle down so you may want to try that.

I would try to adjust the TPS. and Idle screw at the same time. Disconect the TPS conector and see what happends, if idle drops or not

I would run an ecu diagnostic first. Then I would also adjust idle at the IACV according to the FSM, check all vacuum lines, TPS, and MAF.You should be good to go.
