What is it? I've been having problems with my throttle sticking sometimes and my idle and drivability has always been subpar since I've owned the car. I think I may have found part of the answer. The rubber hose that connects into the intake manifold directly under the throttle body is not only kinked like a mofo but also has a 1 inch hole in it. If I'm correct it leads to the PCV valve in front of the engine. Nasty little vacuum leak. So I'm going to try and replace it with some universal hose tomorrow if possible. Only thing that sucks is after almost 3 years of owning the car I never caught it.
