Can't help you without some vehicle/maintenance history...mileage, latest tune up or repairs, etc. It could be a hundred different things from your engine all the way down to a sticky brake pad.

Typically a tune up related issue. Otherwise it's trans TCC lockup oscillation. You want this to be tune up related.
