Dear 206 experts,
Here's a problem that has been bugging me for a while with my otherwise perfectly functioning Peugeot 206 (W reg, 1.4i petrol engine, about 56k miles on the clock).
When I start the engine from cold, the car behaves itself and everything is as it should be. Engine revs is proportional to how much I press the accelerator, idle rev is normal, the car runs perfectly smoothly. However, if I turn off the engine for a few minutes (for example, I stop to fill up with petrol) and then re-start it, something weird happens. To start with the idle rev is normal (or maybe a bit too high but not excessively), but as soon as I rev up the engine to something like 2000 rpm, the revs gets stuck there and only decreases very gradually. The car "drives itself" and there seems to be a power surge: the throttle response becomes very sharp. Then, gradually within a few minutes everything goes back to normal again.
As I tend to do long trips mostly, the problem is not something I can't live with, but it can get annoying.
One of my colleagues - who happens to have an identical model - suggested I check the idle valve. I took it out and cleaned it out thoroughly but it made no difference.
If any of you have any suggestions, please could you share your thought with me.

Not the whole caboodle, only the idle stepper motor (the item shown in Step #13 of the guide). It was sooty but not sticky.

If it has one check throttle position sensor and map sensor.
Also I had one play up similar due to a faulty temp sensor.

1.48V is, I think, combined MAP and temp sensor (MAPT). My money would still be idle steeper motor and / or throttle body.

Do what you saw in the how to thread,and see how it goes,if that didn't help to fix it,then you need a new stepper motor.
