I've had a Mazda 323f for a few years now with no faults. But now, it's running poorly with a loss of power that then picks up.

I replaced the coil pack and it ran great for a few weeks but then loss of power again.
I swapped: plugs, leads, fuel pump. Still no joy and getting ready to get rid of it.

Someone told me that it was too much air getting in. But you do get a smell fuel so I thought the coil-pack may have gone again but sounds alright when engine is not under pressure.

  • Does it have HT leads? Maybe putting the new coil pack on disturbed the possibly faulty HT leads and made it run better for a while. – HandyHowie Nov 7 '15 at 23:48
  • its had two coil packs on and still running but when driving you put foot on accelerator and just wont go starts dying now thinking airflow metre. – ian1917 Nov 7 '15 at 23:48
  • it does have ht leads but the coil packs sit on the top of engine and the two sit on top of plugs then the coil packs each have an ht lead that runs to the remaining 2 plugs. – ian1917 Nov 8 '15 at 0:04
  • If it has exactly the same symptoms as the last time which were fixed when you replaced a coil pack, then it seems a bit of a coincidence. Could you have disturbed something? Did you replace both coil packs? I didn't notice the first time that you had replaced the HT leads. – HandyHowie Nov 8 '15 at 9:27
