I am having the same issue the difference is that i am getting a whistle at around 2k rpms. I inspected my intake boots and replaced the CCV. I am getting it smoked tested this monday. I've read that to completely get rid of p2096 the DME needs to be reflashed. I will be looking into that if have no leaks. Also, i read a thread that pointed to the exhaust cam sensor. I'm no pro, Just giving more avenues to explore.
