Hi,
I own an X reg (2000) Peugeot 306 1.4 (injection not carb) which has
recently developed a problem with idling. When I first start the car it
will not idle it just cuts out and when I come to a stop whilst driving
it also stalls. It does this until the engine is warm and then it idles
very low and occasionally will still cut out. But sometimes it will
idle very low with the engine still cold!
I cleaned the stepper motor (as suggested on other posts) and this
seemed to make a slight difference howver the problem was still there,
so I brought a new stepper motor (£95) and fitted it and the problem
is still there........DOH!

Any ideas what might be causing this, I have read somewhere that it may
be worth cleaning the air intake valve - is this correct?

Please don't tell me that it might be the ECU as I might cry as they
look expensive!!

Many Thanks

Paul
