Well, it's not really a "problem", but here's what happening. Sometimes when I spray, the nitrous seems like it's cutting on and off. Especially through second gear. It pulses like it will spray for 1/2 a second, then stop for 1/2 a second, then spray for 1/2 a second and so on. I found a very small leak right between the two solenoids, but I don't think that would cause it to pulse. I've noticed that it does it worse when I've heated the bottle. Anyway, have any of you had this problem, or know of somebody who has. Your help would be greatly appreciated.
