I have just a minor idle problem. It is the problem that I am having with the car dying in stop and go traffic. If I come to a stop the idle will drop too low and the car dies. It is getting worse. It was suggested to me that it was the idle valve. When I checked the idle valve, I noticed that this hose was coming from the top of the idle valve. I was wondering if this hose being split and not fitting properly would affect the function of the idle valve.
