Hey guys, when I start up my 06 GLI when the engine is cold, it idles pretty rough, but after about only a minute when I put it in gear it's fine. Even when I reach the stop light half a mile from my house, it idles fine. There isn't a hiccup either while driving. I recently changed the plugs and I've read it may be the fuel filter, and I haven't changed it in its 95,000 miles. Is this a good place to start? Any other ideas?
