I have a second hand Smok al85. I was told by my local vape shop that I need to set it for SS for stainless steel as because I use smok coils the SS only shows up in temperature mode however whenever I go to take a hit now it stops mid puff I get one and a half seconds of hit then it times out or something and then it'll pick up again but cut out within a second don't know if it's something I'm doing or if it's the mod if there's a problem with my mod or what that's or something I'm doing if there's something I can do what are your recommendations
