this fixed my problem in less than 5 minutes! my guess is that this hose has been bad for a long time and just recently turned my check engine light on. my car idles like its brand new now and hasn't done that in a long time. So if your looking for the cause of a rough idle check the elbow of this hose even if your check engine light isn't on.
