Don't know what I could have done wrong, and I think I got all the air out of the system.

Vacuumed the system for 1 hour, with the gauges attached and both valves open.
Closed the valves and turned off the pump.
Gauges stayed the same for a while.
Unhooked the center hose from the pump.
Hooked in the R134a.
Releases the high side hose from the car.
Opened the high side valve to allow a little pressure into the hose, and releases a little R134a from the hose to clear out any air. (I know I'm no supposed to)
Closed the valve and put the high side hose back onto the car.
Opened the valve for the low side.
Turn the car on, AC on full with button pushed in.
Released the whole can in the system.
Then released about half of another can in the system.
Disconnected everything.

But who knows, maybe my pump isn't good enough or not working right. I'm not sure how I could test that. I don't see what could be wrong. Oh well.
