A failed or failing coil pack is often the cause for this fault. Only replace with OEM parts as pattern parts are just not up to the job and do not last very long at all.
I checked the ignition coil, changed it to another working one, nothing has changed, perhaps the electronic module but have not found a replacement yet>
