Does yours do the same thing as that guy does in my quote? If so, misfires can happen if the ECU doesn't go into closed loop mode while at idle.
Can you give us a little more concrete info or was it already posted somewhere bro?

 

the more i think about it, my mechanic said it does sound like its misfiring, i know i dont have a lot of information because i'm not hands on with it (due to school and work)
