: 2007 lugging vibration when just cruising around

I bought a 2007 escalade with 65k miles.

I noticed while just cruising around easy on the gas that there seems to be a slight vibration when it goes into the higher overdrive gears. Sort of like a lugging the engine vibration. It is not crazy bad but it is there.

Is this normal? If not would a spark plug change take care of it or anything else?
