My Cars making this annoying loud sucking noise around the upper intake area and the idle is jumping up and down a bit too, which i'm assuming is from this since they started at the same time. Just curios if anyone has any ideas as to what it might be. It's an 09 series 2 .... Really shouldn't be having these kind of issues on a car that only has 14 k miles on it but I did just take a long trip with it out to OK and back. Any ideas would be greatly appreciated, thanks !

 

how loud? I do have a hissing noise up around there too by the alternator, i think that is normal.

 

check under the hood for prostitutes or gold digging women...
okay on a serious note check that all hoses are connected and any clamps are tightened down so there are no leaks..thats usually a good starting point

 

check to make sure the MAF is screwed on tight and not leaking (be careful the screws strip the plastic easily)

 

Sounds like a vacuum leak. Check all the hoses.

 

This...

 

Ok ... No prostitutes or gold digging women, or atleast not under the hood

Someone else mentioned a vacuum leak, sprayed some starter fluid around it and i think i heard the idle drop a little so I'm told that's a good sign it's a vacuum leak. It's not super loud but it wasn't there before, def doesn't sound like the norm anyway. Thanks for the input !

 

There's a hose in the rear of the UIM that has a little white fitting on it ... not sure if its a one way valve or collects evap or what.

I popped mime loose a couple weeks back while (attempting) to fit a filter plate... its about 5" in front of your oil filter... hard to miss it with a flashlight.

And it'll make a really loud hiss if disconnected and definitely eff up your idle.
