if you can't find the vacuum leak look at your gas cap that screws onto your neck of a gas tank take your gas cap off and see if you can move the gas filler neck

    So this problem occurred roughly 3 weeks ago after an oil change (probably unrelated). My Liberty is right at approx 80,000 miles. When I hit 45-50mph or 65-70mph the car will start to "jerk/hiccup"...
