Hi, I recently got into an accident which bent my front bumper in, making me leak coolant, but this also came apart and I have no idea what it is, can anyone help? Its connected to the Intake manifold, I assume it regulates air or something. My car still turns over and runs, but makes a odd noise when this part is diconnected, when fully in, the engine sounds normal. Thank you!

 

That's an ejector, no- not an injector - an ejector. Google it.

You should notice your power brakes don't work well or at all when disconnected.

 

Thank you very much! Yes my brakes didnt work when I tried pulling over!
