very hard to say its one where u need to see the car but
very rare for a new coil to go or even more than one pack to go let alone 3
id try a different garage.are the coils def u/s or could it be the wireing plug to the coil.
air flow meters are rare to go on nissan and o2 sensors very easy to check.dont fit any parts unless you are told they are def u/s
coil packs arnt blown by the car as they are only given 12v or 5v and earth.hope this helps a little
