The front end of my car is starting to get low again. The air compressor comes on every minute or so of driving. I can hear it come on at every stop light.

I replaced both front struts with brand new struts and a new valve block in August 2008. Any ideas why it's dropping again?

This car has taken years off of my life. I'm pondering to just sell it for $10k this summer. I hate it to no end.
