Mazda 323 Misfires Under Load
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.
Engine misfires mostly under load but today it is doing it in idle to the point of shutting off. It seems, it is doing it more after being not driven for a while, at least over night or week-end, or rain. Can it be due to humidity? It feels like after a while that the car is driven, it dries off and then it is fine until the next time when it is not driven for a few days, or it rains. No resolution yet. - Visitor
