New hissing sound
I have a new hissing sound, almost like the fan is still on, but it's not. It's just like the one when my PCV boot had a hole in it, (it's not it though). I was sitting in the driveway yesterday and did a big rev as soon as the rev came down it almost shut off. This has never happened, my mods are in my sig, A4, it seems my RPMs are down a little as well too. What should I idle at? Help me please.
