It will jerk a couple times in a row when I speed up going down the interstate. I recently had an oil change and my tires rotated and balanced before taking a trip 5 hrs. From home. This problem didn't start until I got back home within the next days after.

It sounds like you have a spark plug or a plug wire problem. I'd start there. You may have had your plugs changed before, but with your mileage, your wires need changing too. Replace them all at the same time and see if that helps.
