can any one give me the exceptable range that I should see for the high and low pressure readings for a 2002 montero sport 3.5 ltr?compressor drops the low side pressure reading fast (25) when rpms are up to 2k then above 45psi at idle.

 

35 low side 225 high side

 

Ended up being a stuck expansion valve, it is in the passenger compartment.

 

change to drier also the expansion valve is the same as toyota truck $38.00 at auto zone
