You know, now that you mention it, it did sound a bit louder. Like it could be a louder intake sound. I had my windows down to listen and yes, there was more noise from what I could hear over the road noise. And it did sound like a very loud intake sound. And boy, you right, it runs absolutely horrible. Did you fix it yourself? What kind of job and what was the $$? Wow, this almost relieves me a bit that it may not be catastrophic. I love this car.
