2005 Nissan Sentra Question: Jerking while idling

Just bought this car from a dealer 4 days ago. Today I have noticed some jerking or quaking especially when idling. Could this be a bad spark plug? I'm hoping for a simple solution and that they didn't sell us an expensive problem. -
Answer 1
could be many things - take it back and have the dealer look at it. -
