Clean the IACV/FITV.

 

also there is an area on your throttle body by the Idle Control Sensor you can adjust your idle with a screw driver

 

If you use your finger to cover the port leading to the FITV inside the throttle body, does the idle speed become normal?

 

i used a screw driver to adjust the idle and that didn't help but i took the throttle body off and the FITV rattles if i move it around i think a piece in it is broke so im going to get a new throttle body tomorrow and try that and see what happens
