				How do I check for a vacuum leak?
			 
 
			I keep getting 1411 / 0410 which makes me think I either have a vacuum leak or a broken pump.  I'm not exactly sure how to check for either of those... should I just take it to the dealer? :-/  I was able to replace my Air/Oil seperator so I'm not completely dense as long as I know what the problem is.
