So what is the trouble code?

I'm getting a p0505 code I changed the IAC for the second time, checked the proper voltage...etc now the car won't idle down its running about 1400 rpm even after reading the manual and taking the proper steps to bring down the idle by adjusting the idle screw it won't idle up or down


This sounds like a vacuum leak. Keep checking on the wires and voltages.


This could be a tough one as you've already been very thorough in your response to this matter however I would buy a can of starter fluid and spray across all vacuum lines and intake areas to verify that there are no leaks and obviously the car has to be running when you perform this test it's a simple one but if the idle Rises you may locate an area that is leaking and unregulated airflow will cause the symptom


Furthermore there's nothing wrong with removing that IAC clean it thoroughly with carb cleaner as they are notorious for buildup from the cooling system
