each time i have been advised to use all new plugs. dont know about this time. Something is making them go bad.
Expert:  peterpete190 replied 1 month ago.

O.k.,I would have it checked over/tested to see if the plugs and coils are the cause here again just to be sure.If it is found they are then I would have the engine wiring harness inspected leading to the coils for any issues needing repaired like any shorts or damage.If this is o.k. the only other thing I see is maybe a fault with the engine computer sending a surge causing coil damage with the computer needing replaced.

But I would have this checked/tested further to be sure it is coils again and then checked from there.
