Ok. The system was low of 134a. I topped it off and ac works great now. I’ll have to track that leak down this winter. Now I notice that when at idle when the ac compressor kicks on my engine bogs down to about 550 rpm and acts like it wants to die. When the compressor is off the world is right again and I get my 750 rpm. First, shouldn’t the car compensate for the extra load of the compressor without killing idle rpm like that? 2nd - I am running Oem cooling fans and understand the extra load on the electrical system could be partially at fault. What do you think I can do in order to use the ac without worrying about the engine dying at a stop light? Is the idle control valve a potential culprit?

Thanks in advance for your opinions.
