Peugeot 205 Gti 1.6
Discussion
there is a slot head brass screw (idle screw) on the back side of the throttle body. count how many turns it takes to remove it. clean the screw with petrol and a rag then refit, take the car for a spin to warm it up then adjust the idle screw to give 1000rpm on tick over with the lights and heater on.
hope this helps, if not report back and i'll have another think

Ah, this takes me back a bit!
Between '96 and '99, I had a lovely '87 vintage 205 Gti.
I lovingly cared for and looked after it, as I do all my cars - but even after spending vast amounts of time and money trying to get the Lucas EFI system to idle nicely (including faffing about with all of the items other posters have listed above) the fact of the matter is, one this system has a little use and wear in it, you are basically fecked - it will not ever idle correctly. Some really bad examples (as mine was) will just keep cutting out at traffic lights and junctions
By cleaning and replacing parts, you may get it to behave for a while, but the problem will always come back. It's inherent in the model, basically, and a well-known fault.
The only way I eventually cured it was to fit a new inlet manifold from Datum Engineering, which allowed me to bolt on a pair of twin Weber 45mm carbs! Easy job - manifold, carbs, fuel pressure regulator to drop the EFI pump pressure down, plus a choke cable assembly for a manual choke knob inside the car.
Once set up, she fired on the button, idled as sweetly as a sweet thing, and ran hard all the way to the redline, complete with huge induction noise, best sampled with the driver's side window wound down!
On the rolling road, as a bonus too, she made around 110 bhp at the wheels - even more than a stock EFI 1.9 would.
For not much outlay and an afternoon's work, this mod turned the car into the kind of car it always should have been - every drive was a smile afterwards!
