HI,
Ok, the surging is due to idle fluctuation, either the tp sensor of the iac valve. Your vehicle has an electronic throttle body which means that both of these are integrated into the electronic throttle body.
The first step would be to clean the throttle body.
If still an issue, the ECM should be reflashed for the throttle body parameters and if still happening, the throttle body replaced
