Actually, the opposite happens when something gets stuck in the intake.. My gasket from the y pipe managed to slip out and into the TB and the car Instantly went into heavy limp mode, it idled EXTREMELY rough, allowed no throttle input, and threw a CEL for incorrect values on TB, Shardul actually saved me there too, autozone said bad O2 so i replaced it, then called shardul with the code, and he walked me threw all the way until there was supercharger whines coming through the phone... ![bow](https://mbworld.org/forums/images/smilies/bowdown.gif)

Now I'd like to find whatever attaches the Y pipe to the throttle body so it is on there snug.

This actually happened to me last night. I was stuck in an intersection (not in the flow of traffic, thankfully) and a cop came and pushed me with his truck to an apartment complex where I could turn in. After looking around and knowing I had been doing some work on my car recently, I noticed my Y pipe was ajar and low and behold, the butterfly valve was clamped on the gasket. A quick fix after that I thought "is this the first time I've been stranded with the hood up and actually fixed something?" LOL!

I have a similar noise, like something is loose. Once I start the car I can hear it, if I press the pedal it increase with the rpm. The sound come and goes.
Car drives normal bone stock. Anyone experienced the same problem ?

Try squeezing the two rubber boots that go from the airboxes to the Y-pipe. Each one has a metal ring inside it. You will be able to tell if one side is missing it as it will be easy to collapse.
