Possibly a cam or crank sensor. You need to scan the OBD for fault codes.
HI this is due to bad coil packs as they are not firing and gorunding out , change all the coil packs and plugs while your there and that shoudl cure it . Can also be a bad accellerator transducer (dirty) which isnt getting the signal properly.
