I have an aspire cleito tank with a 0.4 ohm coil that is now whistling when i hit the fire button on my mod. The sound is rather annoying and im not too sure on to fix this. I've tried adjusting the air flow and removing the tank and wrapping the bottom of it with a paper towel and blowing through it to clear out any excess liquid and nothing has worked. Am i doing something wrong or what? How do i stop this? I don't have any extra coils or tanks at the moment so i can't swap one out.
