best way to eliminate is to put no1 sparkplug lead onto no2 sparkplug but leave no2 lead off, if you fire on 3 cylinders still then leads are ok, but if you only fire on 2 then leads need replacing. remove no1 lead and put no2 lead onto no1 sparkplug, if you fire up on 3 then plugs are fine, fire on 2 replace plugs. do the same at the other end of the leads, leave no1 lead off and plug no2 lead into where no1 lead should go if you fire up on 3 cylinders then coilpacks fine if you fire on 2 cylinders then its faulty
