Hi, as far as you can tell im pretty new here. But hopefully I can get some help here because I cannot anywhere else. I have a 99 Buick Century Custom, 3.1L and cannot get the thing to pass emission inspection. My MIL light is on and for a while when I would read the codes I would get just P1441 "EVAP System Flow during non purge". I went and checked everything out from loose hoses to silenoids to leaking hoses, even replaced the gas cap twice and could not find anything wrong. Tonight I decided to take another look and found there is an open hose leading from a vent from the top of my fuel tank. This vent is slightly to the right of all the other hoses coming out. Anyone know where this hose is supposed to go? Because I could not find any other open counterparts that it would belong to, or is it supposed to be open like that? Another thing I noticed tonight was when I checked the codes again I got another P0401 "EGR Flow Insufficient" could this be an underlying cause as to why the first code was given, because that one never came up until now, and the EVAP one has been reading for over a year. Or is it something else completely? Any help would be most appreciated, thank you.
