Rico;
        I can not speculate from those symptoms. Your best bet is to put
a gauge on it.
        I permanently connected a gauge using parts I had laying around
the garage. I left the gauge in the engine compartment. My system holds
pressure for more than an hour after being turned off.

Drive Safely & Good Luck
