Hello mate, don't panic 
Had a similar idle problem on my 2.3 16v at one point, when cold it would start to hunt then gradually get worse until it stalled. Cured it when I did some work on the throttle body, this may well be where your problem is. The idle speed control valve and the throttle position sensor are sometimes culprits, could also be a leaking vacuum hose although I'm not sure about the 12v .
Hope this helps.
Regards, Bruce.

Just solved some problems with my own 12v 2.9, and Bruce is right.
Try removing the plug from the Throttle position sensor. Tie up the plug so it can't get caught in the belts. This is under the idle Control Valve, and has three wires/ pins.
I'd suggest that you pull the clip that holds the plug in with pliers, as if you drop the clip into the engine compartment it's an absolute sod to retrieve.
Then try driving the car again. If there's an improvement, then you almost certainly need a new TPS (about £40.00). The idle control valve may well just need a good clean. ALWAYS use new gaskets on both components. Any air leak will prevent you from getting the idle correct.
DON'T go messing with the throttle control screw (which should have an anti-tamper cover on it anyway). This will not solve your problem, and will probably make things worse.
The TPS gasket is about £9.00 from Ford. Easy to cut one yourself for about 3p out of some gasket paper (most accessory shops have this).
If it's not this, then it could be other things, but need more info from you when you've checked this. Don't panic though. One way or another we'll get you sorted.
Welcome to the site.

There are quite a lot of people now selling the Ford Scorpio Manuals (all types) on CD, on Ebay...............Naughty, as it's copyright, but Ebay seem to be turning a blind eye to it. There's even one guy selling it complete with the Ford logo on it. Last week there was a genuine (?) Dealer disc on there for all the current models.
Ebay 260085911804 and
Ebay 130081502467 for example.
You'll still get ALL the information about your car here on this excellent site, and because we are real life owners of the car, we do know (between us) an awful lot about it.
You can't have a discussion with a bit of plastic disc!!
You'll find the guys here much more friendly and knowledgeable than any workshop manual, and there's usually someone around to help you with any problems, day or night.

Glad it's improved.

Don't take an angle grinder near these components as their adjustment is critical...
The throttle housing is indeed the chunky part that comes after the air cleaner hoses. with 'the two holes'. The butterfly valves and the spindle which open and close as you use the throttle should be nice and clean, and the 'Cylinder' is the IACV (Idle Control Valve). That too needs a gasket to ensure it's airtight.
On one side of the Throttle housing, you have the springs and levers that actually open the throttle. The shaft runs right through the body of the Throttle Housing, and, at the other end, is the TPS (Throttle position sensor), which is the bit I was telling you about earlier.
This is an 'electronic' part, and is held on with two very small bolts (7mm). Try testing it in the way I suggested , which is to remove the 3 pin plug from the TPS (not the TPS itself), and drive the car. If you notice a significant improvement, then there's a good chance that you've found the problem.
Can I finally just kindly point out to you that when you TYPE IN CAPITALS, it is the Web equivelant of "SHOUTING" at people.............
Come back if you need any further help.

Glad to help. I've been working on my own cars and motorcycles for over 40 years....you learn a lot doing it yourself, like the satisfaction of doing it properly, and not getting ripped off by garages.
That's the beauty of this site. We all try to help each other, and I'm sure that as you get used to your own car, you'll be able to help others in due course.
Believe me, there's a lot of very good and very nice guys on this forum.

Hi all, well i did what you guys said and this was the results -
After a good clean up with carb cleaner the idle seemed a lot better but every now and then would suddenly drop quickly and then return. I dissconected the ICV but this made it worse and only tick over at 500 RPM and cut out when it was given a few revs. After re-pluging it back in it seemed ok again and so I took her for a quick 5 min drive, on returning it was almost idling perfect and so far still is, will keep a close eye on it and will report back soon, many thanks

Disaster struck about two hours ago, on my day off and thought id take my misses out in the car. We pulled up to get fuel only for the car to again start idling up and down again, then it cut out. Managed to restart but had to keep revs up to stop it stalling. After a while it ticked over poorly but didnt cut out. About 25 miles later we stopped for some lunch and it again cut out. This time it took ages to start and finally cut out and wouldnt start at all. 30 min later the RAC arrived and althought he got it started said that he could not tell me what was actually wrong without a diagnostic which FORDS charge 76 pound for. Said to also try and clean out the ICV again which im about to do. Any more ideas guys as im now going bald.

OK Does sound as though you have done something when messing about with the IACV..
On the 12v there is a small black vacum pipe fitted under the IACV which is crucial in the running of the car. It fits onto a clear plastic fitting and can easily be left off.
If this is not fitted then you will experience very poor running difficult staarting and possible no 4th gear.
well worth checking this first.
This pipe is on the 2.9 v6 12v engine ONLY
just to help out here is a PICTURE

Check through This list and see if it helps. The IACV can be crucial to the running. Did you replace the gasket ? if not it could be an air leak. Regretfully sometimes the only cure is to replace the unit.

Please re-read my post.
I didn't say disconnect the ICV. I said disconnect the TPS Plug. This is UNDER the Idle Control Valve, and has three (3) pins. The plug is held in place with a spring clip.
Pull on the spring clip, (see my previous post to avoid losing this), and disconnect the plug. Then make sure the plug is well out of the way of any rotating belts, by taping it to something, and try the car again.
If the car runs better, there's a good chance that your TPS sensor is faulty.

Hi again, I will try that tomorow as not had a lot of time today, I was looking at the wrong thing lol, well atleast the ICV is now very clean, ill dissconnect the plug you mentioned (if im looking at the rite thing the unit itself is aprox an inch long and is bolted on by two what could be 6-7 mm bolts with the black oval shapped plate bent over at each end to possibly prevent the bolts loosening. With regards to the kind info sent by snoopy I checked and all the pipes are on, once again guys a big thanks and I know you must be getting bored of me by now, if not my technical discriptions lol, but your help is much appreciated

Hi again.
No..we're NOT getting bored of you. We all help each other here, and that's what makes it such a great site.
It might me ME that needs help tomorrow.
You have correctly identified the TPS sensor!! YIPPEE. We're getting there. You do NOT need to remove the sensor (in fact there's no benefit to doing so, as you will disturb the gasket and possible make things worse, so for the time being LEAVE IT ALONE).
Simply disconnect the plug, being careful not to lose the spring clip which will try to 'ping' off and hide under the engine......I know....I've done it!! >: USE PLIERS.
Make sure the cable can't dangle in the belts, cos it will make a horrible mess of it when you start up!! 
Then run the car again for a few miles. it will run fine without the plug connected, and you hopefully will notice a big improvement to your idle problems.
IF that's the result, then your TPS sensor is probably faulty. They are about £40 from Ford, and you need a gasket (make your own as they are £9.00)!! Even the guy in the parts department couldn't understand why a tiny little gasket cost anything like that.....but there you go.
You can't repair a TPS sensor. They are plasti-sealed electronic units. Don't even bother. Give the pins inside the plug a good clean whilst you've got the plug off. I gave mine a good spray with some WD40 and then let it dry off.
I have exactly the same car as you, so know quite a lot about it. I also had a Granada 2.4i Ghia and the engines are not so far apart.
Hope you get sorted, and don't worry about returning as often as you need to.
