The condition you are describing is normal and still indicates that you need to add freon. A faster spinning AC compressor creates reduced pressure at the accumulator dryer this will in turn cause the low pressure cut off switch cycle more rapidly.

But the weird thing is this. When I'm moving down the road for the first few minutes after start it's cycling quite heavily-- every couple of seconds. But if I'm stopped, or coasting & the RPM's are under 1500, it stops cycling. Then magically a couple of minutes after I get going and after RPM's drop down at least once, it stops and only cycles once every couple of minutes (if that). the air out the vents by then is quite cool and comfortable in this sticky 90 stuff. We did checks for leaks before and after conversion/fill last december, it was ok. Now what? Kevin #4687, Houston [Non-text portions of this message have been removed]
