It depends upon which emissions system you have in your car but if it is the popular one you probably have a faulty purge valve, which is the one by the fan shroud. I have had a couple of cars recently that I had to parts warranty near new valves in because they failed too. Volvo has been having problems with these stupid valves for awhile. You can suck and blow on them and they will seemingly work but under actual operation they will fail. The only way I have to diagnose them is to listen to them work and if they do not have the correct sound to them I replace them. Needless to say that is an acquired thing.
