Help please I have a miss on my zafira 1,6 how can i test the plugs with a one piece coil pack in place . A t one time on a car with plug leads i had an in line tester that would light up if the plug was good. I can't see a way of using these short of buying 4 and putting one on each plug. Is there something i can buy to test this ........Cheers
