Cossie Cold start

Hi all. The project car is having a bit of trouble getting going in the mornings ( dont we all  ). The symptoms are... Takes 3 or 4 turns before it fires & then is lumpy for around a minute. The idle is a little up & down for a while but fine when the engine is warm. When driving the engine will 'hunt' on light throttle, but fine when you give it a little gas. I shall be changing the idle control valve when it eventually stops raining  & will probably change the throttle position sensor & the MAF at the same time, but was wondering if there is some sort of 'warm up regulator' nessled somewhere deep in there ?. As always any advice / opinions are welcomed. Thanks in advance... Craig

craig,
pop the air box off and have a look up the breather tube, see if the damp has turned the oil residue into sludge, also see if the little filter sponge is blocked up (remember your blue mk3)
pop the engine cover off and see if you can hear a small air leak, the little T connector may have broke
i'll be over in the week to give it a good going over on the electrics, may give the engine a going over to

I was just thinking about theTT piece m8. I would make sence considering the symptoms. Think it's time to break out the WD & have a squirt around when the engine is running. If theres a vacume leak that will soon find it

Hi Guys
The T piece is definitely broken on mine but it doesnt seem to affect the running. (Does anyone know where to get one?)
Re the sponge filter in the air box.Mine hasnt got one, is it needed, can you just make one out of a piece of household sponge?

Ordered them last week, will probably soon arrive:
6631943 3.05€ (available), the most likely culprit.
1669273 2.17€ (assumed available from Cologne)
Generic T-pieces won't work, the middle connector of the first has different size (thicker if I recall). The second should be all ends 4mm using logic.
Got all just in case. Prices was from Finnish Ford.
The 90 degree connector 6526351 is also available. Straight hose connector 6753590 is obsolete. But this should be 4mm both ends using logic, hose dimension

Problem solved . Matt & I give it a good going over yesterday and changed.... Idle control valve, MAF sensor, cleaned & re gapped the plugs ( they had been set to 1.2mm  ) & re connected the vacum pipes to the purge valve . Matt also giave the fusebox a strip & clean ( just to be sure ). The end result is the car started first turn this morning despite a heavy last night . Not too sure what the original culprit was, but we are happy little bunnys all the same

Tenfut, check my post above. You get them from FMD. The 6631943 is likelier to be broken, and 1669273 is likely to be a 4-4-4mm T-piece.

Thanks tlundkvi
Any idea if the sponge filter in the air box is necessary, what does it actually filter?

The sponge sits in a small 'box' in the corner of the filter box where the breather enters and is intended to keep oil vapour out of the air intake. I have used a piece of packing foam for ages without a problem. If the foam is in reasonable condition you will see traces of 'sooty deposits' on it. When I 'found' mine it was totally disintegrated into almost crumbs!.

I received all the ordered connectors today.
All were for 4mm hoses, with quit a high expander (at most 6mm).
So what is needed:
4x 4mm 2-way 90 degree
6x 4mm 2-way straight
1x 4mm 3-way T
1x 4mm 3-way 45 degree T (I could have bet my little finger this would have been a 4-6-4 or a 4-8-4 T-piece, when this was replaced the middle was too thin on the regular T-piece we had when we fixed it)
Standard ones would then be fine, if the material withstands heat and has high enough expanders.
Is there anything preventing brass to be used (copper etc.)?
