2.4L Idling Fast / Whistling Noise

[PhilipL]

Hi

 

A few days ago the engine light came on and the engine died momentarily.

 

It runs absolutely fine now and the engine linght no longer shows. In fact I had to do a 350mile journey yesterday and run beautifully... except:

 

1. the engine now idles between 1,500 & 2,000
2. There is a whistling noise that increases with revs.

Fuel consumption seemed OK but I turned the engine off when sitting in traffic.

 

I looked under the bonnet and could trace the noise (I think) to two small tubes (see picture). They are bare and clean so I am assuming they need something on them / something has fallen off?.

 

If i partially cover the holes the idle speed drops and if I block the engine dies. I assume there should be a valve similar to the one on the left>

 

This might be a red herring so please advise if I should be looking elsewhere.

 

Cheers

I'm not sure but one of them should be tapped off and the other should go behind the engine to a vacuum, do you have a loose hose somewhere behind the engine?

look at this video and see if it matches yours:

 

 

Hope it helps.

Thanks for the quick reply. I couldn't see any loose or missing hoses.

 

I can see yours has a blank and a connector but my engine seems a little different as there is another valve on top of the rocker cover near the two open pipes.

 

My Voyager is the2.4L version but year 2003 (January).

I recently found a post with some good manuals for GVs, find it on my profile, download the one for your car, it comes with pictures and step by step instructions. If something else is there, you should be able to see it in the book.

Hi mike, I might be being thick but been through your profile and couldn't find any links to manuals?

Thanks
