Well...good news
Today I added 6oz. of R134a for a total of 36oz in the system.Had some good results with this change.
Here's the data as of today(7/22/04)
At about 1700rpm
low=25
high=peaked at 260
vent temp-44-46F
ambiant temp lower today=75F.
fan on high
Compressor cycled,on for 30sec,off for 5sec.
at Idle(approx.700rpm)
low=30-38
high=180-230
vent temp=44-46F.
fan on high
Compressor DID NOT cycle.
Here's the kicker.
I turned the interior fan on low and my vent temps dropped even more.
at idle
low=30
high=180
vent temp=38-40F.!!!!
Compressor DID NOT cycle.
At 1700 rpm
low=25
high=200-220
vent temp=42-43F.
Compressor cycled,on 30 sec,off 5sec.
So I'm pretty happy with those vent temps.
Thanks to those that made suggestions.
Hope this info. can help others down the line.
