I'm having trouble with both of these issues!!! I have been going through burnt coil after coil with my Protank, even after just one day. Now I just changed out to a new coil and don't have an ounce of suction, it's like trying to suck up a sock. But oh, I'm lucky enough to get a mouth full of juice! Yuck!! So I changed coils, I loosened it, I tightened it, I put in another new coil, then another. I totally took the tank apart and washed all parts in warm water (which runs through everything just fine in water), I changed the settings, I changed to a new battery...nothing is working!! Please, please help! I don't want to have to smoke any cigs:-(
