Technical Coil light

[vincenze]

Coil light starting to flash after ignition. Goes when accelerator is gunned. Does this mean a new coil? I'm quite handy, something a one can do oneself?

What sort of costs involved?

Thanks in advance

Glow plug? is yours a diesel? if it is the chances are its just one or 2 and id not bother tryin to change the ones that are not dead.
Anologue meter one leg to earth other to top of plug see if they are all the same.
