Driving highway fine.  
Stopping at a light, it shakes like a bronco.  
Twice in the past year the cylinoids were replaced. Oil was leaking in to the gas or visa versa

Is your check engine light on? if so do you have any codes you can post?  
just so you know most autoparts stores will check your car for codes for free

The symptom is consistent with a small vacuum leak. As posted above, this problem is best addressed by reading out the diagnostic codes first.
