Engine Size: 1.5
Refrigerant Type: R134
Ambient Temp: 100
Pressure Low: 25
Pressure High: 300+
If I let the car idle the high pressure stays around 260, as soon as I get the RPMs up to 1500 the high side starts rising it has got up to 350, but then I let it idle down. Condensor Fan is on, if i let it idle pressures are fine and compressor will cycle off and then on. Did the mist test on condesor when rpms are up, it drops the pressure down about 20.
Vent temps 50
Evap temp 40
Ambient temp 100
After do some searches, I guess I was being a little paranoid, from what I was reading 100 abient temp, 300 to 330 is common, so I went back out to the shop, started the civic up idled it up to 2000 rpms left it running with a/c on, I brought a themometer out to the shop it is 104 ambient, vent temps 50 degrees, low pressure 35 high pressure never went over 350.

350 is not that out of line in triple-digit weather. The charge (refrigerant and oil) needs to be rather exact on a small system such as that one. Getting 50 degree vent temp at idle is impressive for a Civic.
Thanks for the input MK378, I feel better about it now
