I just drove home from work and my car was acting really strange. The car was extremely jerky when I got on the throttle at all. And when I came to a stop, the idle would go up to like 1600 rpm and then drop down and almost die. At one point, the car died and I had to coast it. It wouldn't start for a good minute or two. I also noticed that lately when I shut the car off, I can hear a whistling noise coming from the engine bay but it doesn't sound like my intake. :thinking:
