As previously stated, there should be a sticker or plate under the hood somewhere that has that information on it. 1.43 lbs. is about 22 and 1/2 ounces. Two of the 12 ounce cans should be sufficient. The best way to tell if your system is correctly charged is when the outlet end of the evaporator starts to sweat. That tells you that evaporation is just finishing as the refrigerant exits the evaporator.
As to gauge readings, the 400psi that the other fellow mentioned is not out of the ball park. That is one reason that the R-134a systems have a high pressure cutout switch on the high side. R-134a does not behave in the same way as R-12. High side pressures can skyrocket for any number of reasons without there being something wrong with the system. Modern systems are much smaller than older systems, and with less volume in the system, pressures can rise very rapidly with little changes in the system. Also, many systems now cycle the electric fans with the A/C. Pressure on the high side can go quite high until the fan comes on.
Latest buzz is that they now want to replace R-134a with something else. What I heard was R-600. Hope not, because that stuff is highly flammable.
