You can pull them off and put a block plate on the intake and exhaust but I wouldn't recommend it personally. If you get it running properly you should actually see some fuel economy come back if its not working properly. Also, if you have any sort of emissions testing removing it could be a very bad idea as it could fail the test (though if its not currently working it should fail anyway).
As far as bypassing it, if its not constantly leaking you could just plug the vacuum line keeping it from opening at all. You can also just remove it and put a block plate on the intake and plug the exhaust port for it as well.
