Hope it helps.
Push to get the whole lot done at once if you can, although if the car is under warranty, you probably won't succeed . car went into the dealers with the usual symptoms, coil and all spark plugs changed. A couple of days later, the warning light came on again. The dealer actually admitted that if one went, it was ver common for another to go soon afterwards !

My car is leased, and I'd lost track of which injectors/coils had been replaced, but apparently they've now done the lot ...just as the car is due to go back !

Time to switch to diesel, I think.
