SES light came on a couple of days ago and went to get code read and it is showing a po507 code for high idle. What should I look for to fix this? This is the first time we've had a saturn in the family and want to get it fixed. It is something with the engine idle control. Thanks in advance for any help. The car has 103,000 miles.Edited by: 99saturnsc1

Try replacing the Idle air control valve. With 103,000 miles on it, it is most likly your culpret

check for vacuum leaks before replacing that, both of my saturns have over 150k on them and the iac valve has never been replaced
