Only doing it on initial start sounds like throttle body still sticking or settling into a position where it sticks as it has been stood idle for a while.
Try giving a boot full of revs before moving off (either in neutral or with clutch down) to clear the initial sticking and after that pull away normally. If that initial rev pick up (in neutral or clutch down) is sluggish but the car can then pull away normally after that would suggest that the throttle is still sticking.
Alternatively remove the intake and get a mate to press the throttle while you look to see what the butterfly is doing. Get your mate to press it down slowly and see how the butterfly responds. Obviously this needs to be with the car cold.

Hi thanks for the detailed reply. I just took the whole throttle body off and cleaned the butterfly etc so I don't think its that.
Someone at work was saying today that this heat we're having could well be causing any air bubbles in the fuel line to expand causing a lack of fuel flow. Then when I floor it to try and clear whatever it is the pressure builds and forces it through!
Is there any way of getting rid of this? Oh and also would Redex cleaner actually clean my fuel filter as well? In case that's a bit choked up like

There could still be electrical or mechanical damage that is preventing the throttle operating normally from the signal being given from the throttle pedal. I may be wrong but I still recommend you try what I have said to rule it out if nothing else.
I have never heard a car suffer in the way your mate has stated. maybe someone else here has but that is a new one on me in 30 years as a mechanic. Still open to learning something new though.

Yeah I thought it was reaching a bit, it's because he's having a similar problem with his z3 at the moment as well. I've always felt that the throttle is a bit iffy in this car, so I'm wondering if maybe the throttle position sensor or idle control sensor is faulty. But wouldn't that set the engine management light off? I'm only getting 32.1mpg at the moment as well according to the onboard computer and that's low for a 1.4 sport

I cant see the redex cleaning the fuel pump.
it reacts with engine temperature and movement to work and clean properly..if your lucky..i wouldnt expect too much from the redex tho man.
As for the fuel filter just fit a new one there only about £9 new and will not hurt to renew at all.
Also for the air expanding in the tank this is unlikely as petrol keeps itself cool so high temperatures are just not present in the tank/fuel pipes.
Ive just read a similar thread with the same symptoms and he sorted his with a new clutch position sensor???this could be to blame???
If you notice there seems to a lot of cars having problems in this weather it seems?especialy the 1.4petrols for some reason?it would be interesting to find someone who really knows the 206 to find out what it is that is specificaly unique to the 1.4 206's and is not fitted to the other cars in the 206 range as it does seem that this running problem is found on only the 1.4 and only in the big heat we are having lately???
For you here i would read all the other similar postings and see if anyones added something that hasnt been suggested here yet and you might find the remedy...if you do then be sure to post it up and help the other 1.4 drivers suffering the summer stalling blues..

Ok interesting, thanks a lot for your input man! I think I will try replacing the filter just incase and check out the other posts. The clutch position sensor sounds like a possibility though from how the car feels so I think I'll look into that too! Thanks agin mate and I'll be sure to post the results for others

I was gonna post earlier in the week, how there seems to be a lot of upturn in this problem, but quite frankly didn't want to appear like an idiot, saying the weather (heat) could be playing a part.
Sometimes strange ideas can spring up surprising results.
Brought back memories of the seventies, being a hgv driver, queues of lorries on the M62 hard shoulder, with fuel lines frozen solid, before they added additives to the diesel.
No mobiles in them days, great fun.

Hey would you be meaning clutch pedal sensor (instead of position) or throttle position sensor? As I cant find anything about a clutch position sensor for the 206

well you should try to have a pedal resting using a pp2000,this only works for motorized throttle body.

Ha-ha yup! I'm exactly the same mate! 
It's still doing it too. Even if you just sit parked and rev it to about 2,000 you can feel the engine start fighting with your right foot as the revs try to drop!
And if you let it, it sometimes stalls!
Plus today my engine light came back on again! About a week or so since I replaced my Lambda Sensor.
(Which is a really horrible task might I add!!  )
Got a used but working MAP Sensor for a fiver on the Bay so hopefully that might make a difference! Worth a go for a fiver eh!
But this problem is really annoying me... although logic is telling me Throttle Position Sensor! ??

Yeah I'm always getting distracted too, I think it's a subconscious way of avoiding the real issues
So today anyway I put the replacement MAP sensor into the intake manifold and reset the ECU again. (sensor was out of a 307 but same thing)
Anyway the light went out but after a while idling, it started spluttering again and almost stalled itself a couple of times like before 
It sounded like there was a pressure problem so I pulled the breather pipe off while it was struggling to idle and it suddenly spat a bit of creamy oil out from the rocker cover. And then it settled down!? So now I'm really confused... and worried it might be taking in water somewhere as well!!
Anyway I don't know what to think now, I just don't know enough mechanically!
I did read somewhere though, that it could be the PCV valve? That could be stopping air circulating properly and that the creamy oil is just due to my constant short journeys causing condensation.
That mean anything useful to anyone?
PS - I get a whooshing water sound in the car when revving up or accelerating straight after the first start. Could it be related?

UPDATE
Ok so, as it turns out, my Head Gasket has gone!
The coolant chemical test went straight to green in a second 
I hope this isn't what is causing the problem for you guys! As things are going to get pricey...
