I have a 1.6 Mk1 Facelift focus (52reg) which is just burning through coil packs... I have replaced 4 in the last 12 months, and the latest one is starting to develop issues at only a couple of months old. The last one was bought from ford for an arm and a leg.
Does anyone know of any issues that may cause the packs to fail? Such as unstable electrical current or anything as wild as that?
