Hard to say where I'm sitting. Why are you bumping up the idle? You should be in the 600-700 range. Something else must be going on to have someone tell you to increase it. Have a reputable mechanic look the SUV over and suggest some fixes that will actually work. 3 mounts at 3 different times? Really?


Is your check engine light on? Your engine could be misfiring. That will cause a vibration that can sometimes be hidden by increasing the idle speed. Not the way to "fix" it though. HTH. -Jim
