Does anyone know the low side pressure when recharging the A/C.

I had my system converted about 3 years ago to r134A. Was working fine but dind't cool as much anymore. Cools better now, but not sure i if i overfilled it...

Does anyone know how much 134A should be in the system ?

80% of 28-32 oz of refrigerant.

I just converted my car to R134a, dumped the remaining R12 out myself (and didn't do a very good job) and put in about 3 4.5oz cans of R134a. The A/C hadn't been working for years, but now it blows ice cold, almost as good as my mom's brand new Saturn....and this is a 16 year old car with almost 160,000 miles on it!!! I just stopped filling it when the A/C got cold.
