Once my ZX3 gets up to running temp it really starts to smell. It's ok when I'm moving along because the increased air flow pushes it away before I can smell it. When I'm not moving however, the smell gets into the cabin air system and fills it with this damn smell. The best that I can tell it's originating from the front of the car. I looked around the see if I was burning a bunch of oil or something but it doesn't really look like it. Any ideas of what it could be and how to fix it?
