Ah, it sounds like you have an American wisteria, likely the 'Amethyst Falls' variety, which unfortunately has a disagreeable odor like that of cat urine - normal for this wisteria. There is little you can do about this since it's normal, though pruning out the flowers or masking the scent with other 'nice-smelling' plantings may help alleviate the problem. Wish I could be more helpful.
I think your vine is likely stressed and may be showing some signs of watering issues.
Make sure you are watering deeply, once or even twice a week with a slow trickle.
Check to make sure the soil is well draining and that the roots are moist, but not soggy.
Here are some links to refresh you on the care requirements.
Amethyst Falls is the most common variety of Wisteria sold in American greenhouses.
This is a common complaint about this plant, though not everyone can smell it.
Many people report 'no smell' and others say 'it smells like roses'.
There is nothing that can be done to change the smell of the plant.
Enjoy from a distance!
