Vamo V3 performance drop

[IShotBigBird]

Lately my Vamo V3 isn't burning as well anymore. I'm getting less vapor. I thought it was the coil but I swapped in a new one and it's the same. I believe its a connection issue because at times it won't burn at all so I move the tank slightly and it works again. Is this the end of my Vamo or can I do something to fix it?

btw, I'm using a protank 2

You might need to pull the contact pin up just slightly.

This video is an ego but it is the same process on nearly everything

In addition to adjusting center pin on the device you may also try adjusting the center pin on your ProTank. Also, make sure you don't have e-liquid in the 510 connection.

Try cleaning the threads using a cotton ball or some qtips and some isopropolyn alcohol. Clean the 510 connector and ego threads.
Remove and clean both battery sections, the battery cap and the control body threads.
