My truck is sputtering on the upper side of the rpms, like a popping/miss, around 2000rpms and up its cutting out, I changed the fuel filter and cleaned the water separator but it didnt change nothing, how can you increase the prussure on the airdog? when I first put it on it was steady around 18psi and now it sets at 14psi and i can pull it down to 10, please help...
