i have a kangertech subvod starter kit i got a couple of months ago and it's been having problems for a couple of weeks now. i can't currently replace the coils but i took it apart and rinsed it all off and cleaned out all the gunk with a q-tip. after i did that, the problem got worse. the hits are really harsh, barely any vapor and it feels like it's clogged. is this all because i need to change my coil? or is something else wrong?
