So at first I didn't have the rattle. Then I took my short ram intake off and put my factory one back on. Immediately, I started having a rattle in the hood release latch when the car was stopped with my foot on the brake in drive. After a few days of being annoyed and seeing how much worse my mileage was with the factory intake on I decided to take it off. Immediately the rattle stopped and it's been that way for a few weeks. Last Saturday I brought the car in for an oil change and the next day any time I am stopped in drive there is a loud knocking type rattle that seems to be coming from in behind the gauges or up by the windshield. As soon as I let off the brake and touch the gas it disappears. It's not the hood release latch because when it was doing it before it was really shaking and now it doesn't. I haven't had a chance to have someone sit with it in gear while I investigate but this morning when I got to work and pulled in my spot it was really knocking so I popped the hood and as soon as I did that it stopped. Any idea what component of the hood release cable it could be?
