I am running r134a. Everything related to the a/c system had been replaced less than a year ago. Hi/lo side are within spec according to chart plus my ambient outside temp which is 90°+. My car does idle up when I turn on the a/c. How can I increase this "mass flow"? My airflow across the condenser from the fans is quite a bit with the 4 fans and the way I shrouded it so that there is virtually no air going around the radiator or condenser. I always do the comparison whenever I am in another car, for example, a friend's '99 E320 sitting in idle and the ac was ice cold. It seems that I have massive amounts of air flowing with the fans compared to the low speed fan of a newer maybe mid 90s car and my system is sub par. When driving it's a different story.
