If you just changed the plug wires, then the likely cause is they are not built correctly or installed fully and the terminal clip in the wire is not touching the plug cap.

Here are some guides that will help with this info. Please run through this testing if needed but I would remove the plug wires again and reinstall them and make sure they click onto the plug.

Unfortunately we don't have a manual on this vehicle as it is not offered here in the USA so I cannot see what type of wire ends this has but I can only assume they are no different then a standard set. However, can you get pictures of these and that may help us determine what the possible issue is?

Thanks
