1998 Acura Integra A/C issues

I have recently reinstalled all the a/c components (hardlines, condensor, compressor, etc.) I added the pag 46 oil and stop leak then 24 oz of r134 refrigerant. Now the a/c was nice and cold for about 20-30 minutes of driving and idle. Then while driving it started getting warmer and warmer. I thought maybe it was low on refrigerant and got another 12oz and put it in. The a/c again blew cold for about a couple mins and the compressor clutch engaged then immediately disengaged repeatedly. Maybe it is overfilled? The clutch does not engage anymore but when I turn on the a/c I do have the fan engage and the relays but just not the clutch. The rpm's usually kick up a bit then drops down but now it jumps up to about 2000rpm and stays there.
