Need some advise

About a week ago I replaced the ac compressor on my impala, I also changed the ac relay.
I added 5oz of oil, my compressor came with three already in it, it called for 8oz total.
After that I pulled a vacuume for an hour and let it set for an hour,It held.

I thank my car needs 1lb12oz of 134a so I added that much, the ac compressor came on and was putting out 46deg. Air from the vent.
When I attempted to remove the gauges from the car the Schrader valves stuck open. I used a valve steam puller to wiggle them and they stopeped. It sprayed out for about 5 second so I don’t know how much I lost.
I had replaced the schrader valves that day but it turns out my gauges are **** and they bend the valve if you turn them all the way in.
After this i was upset and just added the last 10oz of refrigerant I had. The ac seemed to be working fine. The gauges was reading like 50/100. I thank 50/150 is perfect but it was blowing really cold.

So know I’ll be driving down the road, air freezing you out and the compressor just kicks off but if I turn the air off it will come back on in a few minutes and last for a while. nothing looks frozen up under the hood but there is a lot of condensasion on the dryer and it’s cold. I changed the relay again and it didn’t help.
I haven’t had time to put gauges back on it yet but even when I do I really don’t know what I’m looking for, I don’t really know what I’m doing.

As you probably figured, you have too much freon in it now.
Also sounds like too much oil too...
Take it to a shop and have them put a good gauge on it and adjust.

When you replace the compressor, your should replace the accumulator and the orifice tube or you will continue to have problems. These are cheap and easy to access parts so there is no reason not to. Good luck. Take it to a shop and have them fix your current problem.
