I have a 02 a4 Quattro 1.8 t and trying to change the coils any recommendations? It's fully stock and ko3. Also while in idle while in drive and it's on a stop it idles smooth and then throw a little but noticeble "jump". Been trying to figure what it was but not sure precise.... my sparks are msd and they look ok. Any advice or help would be appreciated thanks.
