Driving on the hwy yesterday. I noticed that out of the blue the a/c compressor is cycling on & off almost constantly. I have one of those a/c fill couplers with color coded gauge, green low, blue good, yellow & red, with it hooked up the gauge bounces back & forth from blue to green while the engine is under a load ( about 3k rpm to simulate hwy speeds) at idle the gauge sits in the green & when the compressor kicks on it jumps to almost the yellow. it also doesn't seem to be quite as rapid at idle as it is under a load. it still blows cold so there's no malfunction other than the compressor is cycling on and off. Any ideas?
