Still making the noise on cold start

Duplicate thread deleted. And the noise your hearing is called moosing. If you do a search for it there is plenty of information.
There is an anti moosing kit you can but from fords too.

When it happened on my car it would happen any time of year and any time of day.

There are a couple of cheap fixes one is a small copper bung with a hole drilled in it then placed in the pipe, If you do a search for Moosing then there should be plenty of information.. Ford sell the kits and they sometimes come up on ebay too..

Well worth the money, It's saved me hundreds over the years with the information provided, and i have learnt a lot about the Cougar ..
As above: £18 well-spent IMO...
And yes - it sounds very much liks 'Moosing' - I consider myself lucky in that my current Cougar (my second) is the only one to exhibit this phenomenon out of four 2.5 V6 Duratec-engined cars owned - not all of these engines do it and it's just luck of the draw as to whether your engine and air-intake assembly combination will or not.
It's just a matter of swapping over a pipe on the air-intake bellows - literally a five-minute job (unless like me you try to get around it by swapping other bits from other cars first, then it's a five-minute job followed by a fifteen minute job followed by the five-minute job you should have done in the first place *sigh*...lol)

iirc isn't there a cure by extending the hose to form a loop, and its heater pipe size think it was to buy about a yard/metre or so?
If you look at the air-intake pipe between the air-filter box and the throttle, there's a 'concertina' pipe with four tubes coming off it: two thin ones underneath and two thicker ones on top, with the thickest one towards the back.
That thicker one at the back is the culprit and the one that gets changed: the fix consists of a different shaped pipe with a closed off 'arm' coming off it about halfway along.
When we first discovered what the cause of it was when driving V6 Mondeos in the 90's, some people used to fabricate a fix using a 30cm length of garden hose, plugged at the end and attached with silicone sealant and self-amalgamating rubber tape. Then some people on the Mondeo Enthusiast's Group got together and made a better-looking 'professional' bit of pipe.
Then Ford finally came out with a proper fix, consisting of a new pipe.
There is another fix involving a washer with a hole in the middle inserted somewhere in that tube, but I'm hazy on the details: my first Cougar actually had that washer sat in the boot ready to install (presumably put there by the first owner), but never fitted as the car never 'Moosed'.

found the info the replacement pipe needs to be between 3-4 ft, take from bellows run it towards the strut housing to form a large loop and return to egr valve
fraction of cost of ford pipe, which caused the problem by being too short

Definitely moosing. Mine does it occasionally. I think it's temperature dependant, it's supposed to happen when it's cold but I find it's more a certain temperature range. I don't get it when the air is really cold (sub zero) but at around 3 - 5 degrees it happens quite readily.
I'm not so sure: as I mentioned earlier, only my current Cougar had this problem - my previous one didn't and neither did the two Duratec-engined Mondeos I owned before that.
I've now cured the current Cat's moosing by swapping the standard piping across from the broken car - all completely stock items and upon examination completely identical (though I didn't go to the effort of measuring internal diameters or the wall-thickness of the piping itself).
My theory is that it is more to do with manufacturing anomalies of the tubing itself, otherwise why would some engines do it and not others? In line with most manufacturers, Ford will source plastic items from a variety of sub-manufacturers - something as bizarre as the anti-slip agents used in the manufacture of the plastic polymers that the 'rubber' tubes are made from could be the cause of this.
Ford's current 'fix' is more of a belt-and-braces approach based on what Mondeo enthusiasts were fabricating themselves - initially they were at a loss to explain the phenomenon.
On the 3.0l Duratec fitted to the Mk3 Mondeo, some owners found the fix included swapping the Idle Control valve - something US owners of Mercury Cougars and Mystique cars and Ford Contours also identified as a possible source of the problem.
