I filled up my ac with the R134 bottle from Strauss, now once i put on the Ac my car idles rough and at low rpms. Did i overfill it and its havin trouble turn over the compressor? Wat can this be?

 

Check the low-side refrigerant pressure. If you bought one of the refill kits with the gauge, it will tell you how to check the pressure. If you bought one of the cheaper kits without the gauge, you may have overfilled the system. Go to the parts place and get a gauge.
