My name is Dan and I live in Livermore, CA.
I just purchased a 2005 Jeep Wrangler Rubicon from a dealer. It has 50,000 miles and is completely stock. My question is close to another post I read yesterday regarding the vacuum hoses.
I also noticed that my central vent did not blow air. I also traced the vacuum lines and noticed that the intake hose was disconnected. So I connected it and air began blowing from the central vents. All was good so I thought.
When I took the jeep for a ride, and coming to a stop, my idle would surge back and forth continuously until the motor died. So I pulled over and disconnected that vacuum hose and it runs great again.
Any ideas or similar experiences would be greatly appreciated.
