Had local garage scan car and they gave me these codes
005663 plug 6
005662 plug 5
005661 plug 4
005560 plug 3
005659 plug 2
Is it possible that 5 out of 6 are not working or is there something else that could cause this .not sure if they been changed before but car has 253.000 miles on clock.and it they are all broke do I need metal or ceramic as not sure the vehicle reg is Gj57 GTY
Thanks
