I’m just replacing the coil pack and leads on a Tuscan I’ve just purchased. I haven’t started the engine yet as it’s been stored for two years, so wanted to change oil, filters, fuel etc.
I was also told it wasn’t running beautifully when it came in and it sounded like cylinder six was mid firing occasionally. After a bit of investigation people’s consensus is to change the coil pack, leads and plugs.
On taking the old coil pack out I’ve noticed that lead 6 and 4 have been swapped around. Is this common?

Yes that’s correct. It doesn’t follow the firing order that is marked on the coil.
