Okay, I have a 2004 Jeep Liberty. What the deal is that once it gets to 30 mph it hesitates and then will finally go quickly up to 50. Do you know what this could be?
My friend had the same problem but not in a jeep. I looked at his engine, and looked at the vacume hose to the intake manifold, that was loose, so I tightened that, it fixed it. It could be that, but I am not 100% sure. But it could be many other things, such as your spark plug, or your plug wires them selves.
