P0507 = Idle Speed Higher than Expected
There was a TSB (02-36-022-1) about that code that may be a possible solution. Basically the cruise control cable is out of adjustment and too tight making the idle speed too high. This may or may not be the problem but it's what I would check first before getting into the Throttle Position Sensor and Idle Speed Control actuator.

This TSB has been revised to include additional diagnostic trouble codes and adaptation clearing instructions.
DESCRIPTION:
This bulletin provides diagnostic and service procedures for a vehicle that may experience engine RPM fluctuation and also exhibits some or all of the following:
- The vehicle has less than approximately 2,000 miles on the odometer or the vehicle has had the cruise control cable removed recently.
- The TPS Adaptation Value (as displayed by the Hi-Scan Pro in the "Current Data" Menu) has reached its maximum value of 29.9%. A common value is typically less than 10%.
- The TPS Value (as displayed by the Hi-Scan Pro in the Current Data Menu) does not increase until the throttle pedal has been depressed about 25% of its normal travel.
- The vehicle may also have a higher than specified idle and DTC P0507 (Idle Speed Higher Than Expected) may also be found stored in the ECM.
- The vehicle may also have less throttle response than expected. - The ECM may have diagnostic trouble codes P0121 (TPS Plausibility) and/or P0123 (TPS High Input) stored.
This TSB applies to the following models:
- 1999-2002 Sonata V6
- 2001-2002 Santa Fe V6
- 2001-2002 Elantra - 2003 Tiburon (both I4 and V6)
POSSIBLE CAUSE:
The cause of the condition may be a cruise control cable that needs adjustment.
A cruise control cable that needs adjustment may be positioning the throttle plate slightly open, causing all or some of the symptoms mentioned above.
REPAIR PROCEDURE:
Correct the condition by creating a slight slack in the cruise control cable.
Adjust the cable at either the throttle body end or the cruise control module end (depending on the model).
There should be approximately 1 to 3 mm (1/32" to 1/8") of slack when the cable is pushed sideways lightly (see the picture below).
RESET THE TPS ADAPTATION VALUE by using the Hi-Scan Pro. In the Hyundai Diagnostic Engine Menu, there is an option (typically #10) for "RESETTING ADAPTIVE VALUES" . Do NOT disconnect the battery power. This will cause the Readiness Monitors to be reset as-well-as any TCM adaptation values.

Yes, after checking the cruise control, check for any vacuum leaks, leaks in the air intake (especially after the throttle body), the EGR valve leaking vacuum, abad or leaking PCV valve, bad IAC (idle air controller).
