My 2011 is a little to a lot noisier than usual when the engine is cold, it idles rougher and has stalled when coming of the expressway a few times. From what all I've read, it sounds the symptoms of an EGR valve being stuck open. The code in the computer was a P0300. Looking at various parts sites, I can't find an EGR for a 2011 Versa. Is there one on there and where should I be looking? I wanted to make sure the vacuum lines looked okay on it and the wiring harness.Thanks.
