Ford V6 Idle problem - AdyBeee
Hi all,
my Mondeo ST200 4dr <---- Limited edition 8), seems to have an intermitant problem. When I press the clutch to change gear, I notice the rev's dont drop. What ever rev's I'm at when I change it just stays there.
It's a tad embarasing waiting at a junction doing 5000 rpm.
Is this a common problem with the Ford Duratec engine? I seem to remember something being mentioned to me years ago when I had an ST24.
The car is a 2001 Y reg

Many thanks AdyBee...

It's a common problem on all Ford engines seemingly. My 1.25 Fiesta did it as does my Focus.

I've learnt to live with it. It doesn't do it all the time and it's done it since it was Dad's and nothing untoward has happened.

Look on the bright side, it makes smooth gear changes all the more easier.

Sorry I can't be much help - someone no doubt will be able to advise you more helpfully shortly.

Using the forum search I found mention of "throttle hanging", which is common on these engines apparantly. Anyway, there was mention of a fix over on fordmondeo.org. A quick search over there found this:-

Not sure if that helps at all?

I have a 1/2" copper pipe cap in my tool box. It seems an odd fix though in restricting the flow to a valve. The site says the ECU will sort its self out.
I have just re-installed the Ford ECU settings from the Bluefin settings previously installed. I'll run it for a week and see what happens.

Cheers AdyBee...

The problem is possibly not throttle hang if the revs stay high at whatever revs you were at before you press the clutch. Throttle hangs is normal and only lasts for a second or two when you change gear and is designed to make changing gear smoother. If yours is revving as high as 5000 revs at junctions then you have a problem. I had this on an 1800 Escort zetec. It could be one of two problems.
Try cleaning out the idle speed control valve. This maintains an even idle speed by varying quantities of air entering the engine though an auxilliary passage. The valve is controlled by the ECU. Take it apart and give it a good clean with carb cleaner from Halfords.
Also try resetting the ECU by disconnecting the battery (negative lead first)for an hour (make sure you know your radio code or use a memory saver) When you reconnect, the ECU has to relearn its values. Do this by starting the car and running it at as close to idle speed as possible until it reaches normal operating temperature. Then run it at 1200 rpm for about two minutes. Next drive it for about 5 miles of varied driving conditions.
You can also reset the ECU by removing two fuses but I can't remember which ones they are.
Try going to www.fordmondeo.org and look there. A good site.
