What does it read when the AC is off? In hot weather it would be higher than that
50 PSI at idle would not be unusual, but it should drop as you rev it up to something in the 30's or 20s
You do need both gauges to truly knwo what is going on
With engine off, 50psi. With engine at idle, 50psi. I didnt go above idle.
Ill try it again once I have the dual gauges.
The rpm changes as expected when engaged. Speeds up when disengage etc. Ill try physically see it.
Can a system go from being correctly charged (or atleast working) to being over charged by itself?
