So I just bought my 98 A4 1.8t last week, and it ran fine for about a week. Now last night it started to idle rough and now today the only way to keep on it is to give it a lot of gas. Also its making a whoosing noise. today changed the spark plugs and no change. Where should i go from here? any suggestions appreciated!

 

also cel came on and we went to auto zone and the code was cylinder 1 misfire. and that was the only error.
