I made up some of Chris Lilly's Pork Injection as follows: 3/4 C apple juice 1/2 C water 1/2 C white sugar 1/4 C table salt 2 TBS worschestershire sauce (NOTE: this recipe is for 2 butts. I made a double batch)
First off, I am no expert and I dont own a digiQ but here is my take on it.
If the temp was increasing and the digiQ is sealed at the fan, you must have an air leak somewhere for the temp to increase. Fire needs air to burn and if your fan wasnt going you are leaking, probably from a bad gasket or misaligned dome.
