I just tried this...I bought a can exactly like yours, and when I hooked it up, the pressure reading was WAAAYYYY in the red zone. like 150 psi. WTF thats impossible, I have never recharged it in the past, and have never had a problem with my ac until recently . So I just pulled the trigger real fast to see what happened and it went down to 0 I let go again and it went right back up to the same spot

. did I get a faulty can perhaps? My system takes forever to start cooling, but when it does work, it works well. any pointers? :help:
