what caused you to replace the wire? did you replace the spark plug as well?

Recheck all the wires. You likely didn't seat on all the way.

yes change plug as well and i check them twice i will recheck

Test the wires. Wouldn't be the first time a wire came out of the box bad.

did u change wires and plugs because of a engine miss if so u may have a bad injector if u still have the miss
