You are talking code P0307 each time?
The coil, the plug, the fuel injector or there electrical connectors can all result in the same fault code.
Water or oil intrusion can also be a factor.
Unless this is all a coinisidence, which it could be, one of the other reasons is likely the real fault.
Never fail to at least remove the plug and look at it an inspect oyther parts involved.
P 0307 is a discription of total cylinder performance and does not sort out a specific part as the reason.
