Clean that condenser. Anything under 45 is good for a R134a system. Some get colder but some struggle to stay below 50.
Is this idling or sitting still at 1200-1500 RPM or rolling down the road at a constant 35-40 mph?
You need to get some gauges on it to see what the readings are.
I am guessing you are a little low on refrigerant. Does it cycle the clutch on and off ever? What about if you hold rpms in park at 1500? Does it cycle clutch?
If your low side is barely above the low side switch cut out which is about 22 psi it would be low enough to not cool its best but still keep compressor on all the time.
I never have worked in 117F temps so I would have to refer to charts. but in 85-95 temps the low side should not be over 40-42. 32-37 is good if it's cold and sweating a lot on the accumulator bottle and the low side line.
This is at 1200 rpms as the low side will be a good deal higher at idle.
