CTIS problem

[Bdizzle]

I have a 96 H1 and woke up yesterday morning with the front tires flat. i aired them up and when the quick disconnect valves are connected (front only), the tires will go flat after a period of time (usually about 4-6 hours). If the quick disconnect valves are disconnected, the tires don't delfate, but then the "tire low" light comes on when the beeping alert. I am trying to isolate my problem, is it a leak in the CTIS, problem with the guage...?? Has anyone had this problem? Thanks!!
