jazz 06 spark plugs

[EXT]

  hi,  got DSi 06 modal jazz with 8 plugs ver. car was jerking most of the time when driving in 4,5 gear. the service was not dont by honda when i checked the service book.now when i disconnect
back 4 of plugs wires from the coil is no more jerking at all.its mean some plugs in the back are gone.
question is it is safe to drive for engine or for any other parts with front 4 plugs?? until going for service.

If the service was not done by honda I would check the plugs as heard a lot that the back 4 plugs are not changed.
