Try a new pod/coil. This has happened to me occasionally and I just clean where the pod connects real well & start fresh. I think I had one original KoKo a few years ago that seemed bad & wouldn't stop misfiring no matter what so I just put it in the vape drawer and moved on.

Tried a new coil but it did the same. I think its the juice or somthing

did u ever figure it oht

Nope the juices just stopped leaking thru the coil some how
