P0507 is a generic OBD2 diagnostic trouble code (DTC) referencing a fault within the idle control system. This code is related to P0505 and P0506.
The P0507 code means the idle control system has excessively high RPM. The ECU has a specific rpm range the idle is allowed and when it is higher than expected the ECU sets the P0507 code. Once this code is triggered it puts the vehicle into a failsafe mode and the Check Engine Light is illuminated on the dashboard.

Mistakes are made when simple items are overlooked due to not following steps in the proper order or not performing them at all. A few different systems are involved in the P0507 code and if one system is overlooked parts that are working properly may be replaced.
P0507 should not prevent the vehicle from driving to a safe location once the malfunction occurs. The idle fluctuations may cause the vehicle to have trouble running but in most cases the engine will not die.
The idle air valve and the throttle body can build up excessive deposits of carbon over time usually over 100k miles. This buildup can cause issues with the operation of these parts by clogging them or stopping proper movement. A throttle body cleaner can be used to removed the carbon buildup.
