Welcome to the forum, time for new leads perhaps...

You can buy a set from ECP or individually from from the dealer.

Also be aware that the engine in your car has 12 spark plugs and leads and I think that the leads from the ignition units are different length.

If you can access the lead in question you could try a blob of neutral cure [ not the common or garden acetic acid stuff!] silicon sealant as a temporary fix. Silicone Adhesive Sealant : Epoxies & Silicon Sealant : Maplin Electronics If the problem is localised mechanical damage to one lead fine. If however its an indication your leads are past their sell by date a new set of leads is the answer.
