My s4 tII is occasionally bucking at high rpms. I havent done anything yet to it, but my first thought was maybe I have a plug wire failing at low load high rpms. Im going to change the wires and plugs in a few days. It happens between 4-5000 rpm and feels like a split second of power loss. This may happen about three or four times then once up to 5000 the car pulls real strong and has smooth acceleration. I know I should of changed the wires and plugs before I posted, but while I was waiting for the order to get here I was wondering what else this could be?

Any advice would be appreciated
