a/c issue

ok.. short and sweet.. a/c works fine and cold at idle, but when I take off or my rpm's are up, you can almost immediatly feel a different in air temp getting warmer.. not hot.. but deffinently not as cold as it is at idle.. for me that seems weird, because you would think that it would get colder as you move to do the pully for the compressor turning faster, but hey I'm on an a/c tech.. and yes I have plent of r34 (<-- I think) in there, cause I tried to recharge, and it wouldn't take any, hell a tiny bit came out of the system.. not enough to matter, the only thing I can think to do is get an a/c flush, which I'm sure isn't cheap, and I'm a do it your selfer, so I'd rather not.. any ideas?

It may be overcharged. What are the high and low side pressures? I'd NEVER add r134a without knowing the pressures.

Mine is acting just the opposite. At idle my A/C temp is at 80 degrees once I start rolling it drops to 60 degrees. I assume it is due to the fan not pulling enough air to cool the core.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
