Fiesta Idling Problem,

ADT168 · 08-03-2012, 06:44 PM

Hi people,
I have a Ford Fiesta 1.4 zetec,petrol, 2003, 64,000 miles,
The problem i have is starting from cold,
The car will not idle and cuts out, if you hold the throttle it will idle ok till its warm,
once warm the car is ok,
If you pull away when it is cold, you will get to a junction and it will cut out,
the car does not run lumpy just cuts out,
i have had the car plugged in to a diagnostic machine, (no codes)
I have cleaned the throttle body, cleaned the map sensor,changed the fuel regulator,
and changed the fuel filter to a original ford one,
I just dont know what to do next

Has anyone had this problem and found the cure?
Any info would be appreciated,
Regards ash

I think i have found the fault people,
the crankcase breather pipe has a split on it

Have you replaces that pipe.Has it cured it.I know the idle speed control valves go faulty on these engines.It should be on your inlet manifold.

if its a mk6 fiesta im sure its incorporated in the throttle body

I have got a replacement pipe and fitted it, it seems to be ok now,
I think the idle control is incorporated in the throttle bodie as b19 jub has said.
Thanks for the replys people,

This is a common problem, had it on my Focus. Copied a previous post I made about it...

Part number from ford is FMU 1337254 and I paid £12.15 for it.
The hose just pulls off, I removed the idle speed control valve (and if you have it) the wiring going to the MAP sensor.

A little bit of oil on each end of the hose to push it on and some patients. Will go on eventually.

This is a picture I took showing everything I removed

Think I've named it all.

Have fun
