This sounds like an engine misfire. Have you noticed the check engine light on? If so, then we need to run the codes, have you done a tune up recently? A tune up may fix the problem, it could be just worn-out spark plugs.

Here are two guides to help us with instructions in the images below to help you with your car:

Spark plug specs
1.1 mm (0.043 in)
20 Nm (15 lb-ft)

You should also service the throttle body.
