Hi silver...yes it did straight after I changed it ....I did try swoping out coils but still the same thing happened and I always make sure coils are tight enough but still able to be opened with your fingers ....so I took it back to the shop I got it from and the guy checked it out and said its some factory defect thats why it did that and took it back and discounted an I just 3 for me which all I can say so far is WOWHi @New vaper1
Difficult to say without seeing the device
You say the problem started after changing the coil - are you sure you put the coil in properly ? And tight enough?
Maybe try another coil and see if it still leaks
