Hello I recently bought a 2008 Volkswagen Passat and it started idling roughly not long after I got it. I had it scanned and the codes P0171, P0300, P0301, P0302, P2181, and P0441 came up. I took it and had the oil changed the next day and I was about 30 miles down the road when I heard a sound like a gush of air and it died and the EPC light came on. I have been unable to get it to start since. It cranks and tries to start but will not start. Help???? Any ideas on what this could be???
