Chrysler Repair: Error Code P0507, air induction system, vacuum leaks

Question
Hi Kevin-

I have a 2006 Sebring 2.4L convertible and it is showing error code P0507.  I know it indicates that the idle RPM's are high, but what are some steps I can take to repair this myself?

Also, where exactly would I find the EGR valve assembly on the engine?  I found a suggestion about cleaning that component as a possible solution and would like to give it a try.

Answer
and EGR  unless there is a vac leak from a metal line or a gasket  an egr will not cause high idle being clogged up so that is a waste of time.

P0507-IDLE SPEED HIGH PERFORMANCE
When Monitored: Engine Running. During an idle condition.
Set Condition: If the engine RPM does not come within a calibratable high limit of the
target idle speed, a failure timer will increment. When the appropriate failure timer
reaches its maximum threshold without sign of RPM trending towards control, a soft fail
is generated. When a calibratable number of the soft fails is reached, a 1 trip fault is set.
When two 1 trip faults occur in a row, the DTC is set and the MIL illuminates.
POSSIBLE CAUSES
GOOD TRIP EQUAL TO ZERO
PCV SYSTEM
IAC MOTOR PASSAGES
VACUUM LEAKS
AIR INDUCTION SYSTEM
THROTTLE BODY AND THROTTLE LINKAGE
