Stalling at junctions on run down 206

[PattoJ]

Hi everyone, I've got a peugeot 206 (year 2000, 1.4, petrol, Tu3jp) which has done 119k. It has a problem (which is Apparently common in pugs) where if I'm coming to a junction and at lower revs and take the car out of gear it cuts out (like I've rotated the key back one notch, smooth cutout but all test lights come on) and the steering and brakes no longer work as intended. I restart with no trouble every time no check engine lights and if I take the car out of gear at higher revs slowing down the revs drop at a weird rate sometimes, not smoothly.

The car always starts first time and drives smooth, it has been serviced recently. You wouldn't know the car had a problem.

I did some head scratching and changed my gearbox speed sensor, my stepper motor, MAP sensor, coil pack, crankshaft sensor and fuel filter and have cleaned the throttle body and associated bypass bits and checked the pipes for a vac leak.

I have trawled the forums, including this one which I have found to be practical and helpful in the past. There are topics of this nature in this forums history but this is a little different as I have changed a few quids worth of parts now and am losing my mind!

Can anybody shed some light on this problem or how to fix it?

Any help would be greatly appreciated

Cheers

The car only stalls when I'm slowing down enough to change gear IF I take it out of gear aka at a junction, if I take it out of gear while cruising it runs fine.

So let's say I'm in third going about 27mph, I have to stop at a roundabout I brake down to the lower end of the revs and take it out of gear-it cuts out

Or I'm on the motorway in fifth at 70, I have to brake enough to change down it cuts out but doesn't seem to do it every time at higher speeds. I'm trying to mentally log the threshold of when it stalls, it definitely feels like either the message isn't getting through to the idle speed control valve or the valve is knackered (I have changed the valve so it can't be)

On another forum in somebody else's case it suggests changing the spark plugs but my car runs perfect I can't see it being the problem?

Another suggestion was that the car has a bad gearbox earth which would confuse the Ecu?

Thanks very much for your replies folks, it's always a help hearing other people's situations, I'll try the above methods and get back to you with any results!

I'll have a check of the invoice for the coil pack, may have been the HAAS one. Either way I changed it over after a while of having the issue and the car seemed to be more nippy (although I'm thinking this is a placebo due to my wallet being lighter)

I've got the OBI2 reader on order and have the app, don't know how far I'll get on the free version! May have to fork out for the full version..

Its a bit of a cow because although I've just changed my driving style by dipping the clutch I want the darn thing to work as was intended!

Well, got my Bluetooth connector in the post, low and behold it won't connect to my Bluetooth.. It's probably something I'm doing wrong, me and technology don't mix.

So I did some runs to check the parameters of the stalling..

The car will happily go from first to third with really low revs in third (less than 2000) while accelerating no problems, never cuts out.

However if I were to be coasting down on a level road slowing gradually in speed and take it out of gear at 2000 it will cut out.



Higher revs (2500) will usually kangaroo down to about 5/600 (almost cut out) then zip back to normal idle (hot=900) immediately after.

I think I must have a fuel related problem?

I will fix the sod one day if it kills me!
