306 Auto no Idle

Hi,

Well my g/f seems to have a little problem with her N'Reg 1995 Peugeot 306
1.8 Auto, and wondered if anyone on here could help me solve the problem.
The car has only done 41,000 miles from new and started to stall when she
would slow down for traffic lights or junctions. Seeing that it was an auto
I thought I would do the age old trick of changing the spark plugs.
So the car runs fine for two days solid but then one morning when she goes
to use it, it won't start, I go out and start it by actually holding the
throttle down a little, and it springs into life but won't tick over... I
let the car warm up and it then idles fine. Being a little nervous of using
it my gf decides to catch the bus that day.
So later that day (around lunch time) I come home, try to start the car, and
its the same situation, won't idle but revs fine, when it got warm it was
ok.
The next day I take it to my mechanic and ask him to check this like the
idle control valve (stepping motor), throttle bodies, vacuum pipes.. normal
stuff...
That afternoon he brought the car back and said the car cuts out when it
gets warm, but couldn't solve the problem. He had cleaned the Idle control
valve, throttle bodies, checked the vacuum pipes.. but it was now doing the
opposite of what it was doing the other day...

1st problem was - cutting out when warm...
2nd problem was - not running when cold.....

After cleaning it all...

3rd problem was - cutting out when warm...

So here's the situation, my mechanic recommending I take it to a local
Peugeot dealer to have it put on there computers to diagnose the problem...
The only problem with that is that the car is an auto so I can't tow it, I
don't really want to drive it and have it stall all the time at junctions
and round a bouts.. or possible stall on the dual carriage way.. power
steering and braking would be a problem..
As the dealer is 30miles away.. the cheapest I can find a lifted toe is for
about £200 ! and then if I did get it there... well they charge over £80 and
hour !

I was wondering if people thought like me that it had to be the idle control
valve as what else could it be...

Any help or info would be thanked !!

Cheers Paul

 

Is this the Marelli fuel injection set-up? If it is, check that the rubber
sealing ring between the plastic tube from the air cleaner and the
carburettor substitute (for want of a better description) is still there.
They can get slippery with petrol and pop out. If you can find it, dry it
and put it back securely, otherwise cut yourelf a thin rubber strip, wind it
round a couple of times and clamp the pipe back over that.

How can I tell which one it is.. thanks

I know you can't bump start an Auto, but as far as I know ,as long as its in
Neutral (N) rather than park and the hand brake is off then you can tow it.
Try it , put it in (N) brakes and hand brake off and give it a push, Make
sure when you tow it that the ignition is not locked? I can push my old auto
jag back on the drive when its in (N)

It's not a question of bump starting it, it's that some auto boxes don't get
lubricated properly when the car is being towed. I have no idea if the
Peugeot one is like this, but if it is it will say so in the driver's
handbook. Which no-one in this group ever seems to have ;-)

It could be the servo motor for idling. If you know what you are doing, you
can take it out and clean it and put back try again. It's on top of fuel
contol inlet flow measuring chamber.
