I was trying to measure my A/C pressure in my 2001 Jeep Grand Cherokee Limited with a V8 and the engine would cycle casuing the A/C pressure to read high (over 45), then go low (under 20). Which pressure is the accurate one for gauging if my freon is low. Thanks in advance for any advise.

You want constant pressure. Not a dip.
