A friend of mine had one of their ignition coil snap in half, which meant one cylinder wasn't firing. She drove for approximately for 10km, before getting back home and finding out what was wrong.
We will be replacing the cables tomorrow, and I was wondering would we need to change the spark plugs too? Or would they not be damaged enough to prompt a change?
The car is Renault modus 1.2 2009.
No, you'd not necessarily need to change out spark plugs. The single plug may have some fuel build up on it, but as soon as it starts firing again, it should be okay. If it isn't, then change it at that time (my bet is on it will be just fine).
You shouldn't need to change out plugs but at the recommended service level. That said, if you're close enough to that mileage, you might want to think about it. If you're not anywhere close to it, just run what yah brung.
