anyone hav any idea what a solution could be?

when coming to a stop after moving any speed with and revs over any distance the car seems to drop well below idle rpm and feels like it is about to cut out never has but it is fairly irritating and am worried it may lead to bigger issues, any help is appreciated, my first thought was the idel speed controll valve

There was a TSB to resolve this sub-idle problem issued many years ago. Can't recall the number off the top of my head - I'm sure someone else will though.

first clean out the ICV, soak it in some petrol but keep the electric connector dry. Leave it or about half an hour to an hour then leave it dry over night some where warm to make sure all the petrol evaporates. Renew the gasket and see what its like :D

I will look for TSBs now.............

TSB Search Results - Puma Racing
13/07/06 Unexpected loss of power steering assistance; damaged electro-hydraulic power steering pump caused by water ingress
73/2005
Should a customer express concern that there is an unexpected loss of the power steering assistance, "POWER STEERING FAILURE" is displayed on the instrument cluster and DTCs B1342 (Electro-hydraulic power steering defect) and/or C1099 (Electronic power motor malfunction) may be stored in the power train control module (PCM), the probable cause is a damaged electro-hydraulic power steering pump caused by water ingress.
To rectify this concern a new electro-hydraulic power steering pump has to be installed and a repair wiring harness has to be assembled to the production engine compartment harness. This is then routed along the front of the vehicle to the engine compartment junction box (fuse F2).
The original negative wire has to be fully removed from the vehicle. The power steering positive terminal and fuse eyelet have to be cut off. The open wire ends then need to be insulated to prevent any short circuits.
All parts removed should be sent back to the Parts Recall Center for further investigation. Do not grease or repeatedly disconnect the power steering pump electrical connector to try and remove corrosion.
28/06/06 Stuck in gear / hard to shift
38/2006
Should a customer express concern about stucking in a gear or hard to shift, the probable cause is a loose gearshift cable and/or a loose wedge pin nut. To rectify this concern each gearshift cable should be checked and, depending on the cause of the concern, the wedge pin nut should be checked and tightened with the right torque.

24/05/06 Key cutting/ordering
72/2003
This bulletin contains information relating to the key cutting equipment capable of cutting the 2-track external wave key introduced on Focus C-MAX 2003.75 (06/2003-). This equipment is available through the Ford Service Equipment (FSE) Program.
In addition, for Authorized Repairers that do not have suitable key cutting equipment, this bulletin contains a list of Ford nominated locksmiths that have the ability to provide a key cutting service for the new 2-track external wave key.
Genuine Ford key blanks should always be used when supplying additional or replacement keys to Ford customers. These can be identified on the relevant Parts Microcat.
Further information relating to the 2-track external wave key/lock system can be found in the Focus C-MAX 2003.75 (06/2003-) introduction TSB, number 63/2003.

12/05/06 Intermittent working conditions of fuel fired booster heater
30/2006
Intermittent working conditions of fuel fired booster heater can lead to early contamination of the glow plug and heating chamber. These failures reduce the working performance of the non programmable fuel fired booster heater.
For a customer paid request, dismantling of the outside air temperature sensor and the installation of the Kit - Fuel fired booster heater including a new timer that will be driven by the customer, will enable the system to function under customer control.
This kit should be installed to prevent the excessive smoke related with the intermittent drive conditions of the customer (frequent stop-go situations).
The programmable fuel fired booster heater must not be operated at filling stations. Allow for the extra three minutes of heater operation when refuelling. The location of the timer on the instrument panel should be discussed with the customer.

27/03/06 Replacement of the accessory drive belt tensioner bracket or the idler pulley
18/2006
Because of damage to the threaded hole during the re-tightening process, the pulley located on the tensioner bracket (Part Number:1S4Q-6A228-AE: Finis Code 1 351 134) should NOT be removed. The pulley is NOT a serviceable part and does not have a part number.
The accessory drive belt pulley retaining bolt must NOT be unscrewed/re-tightened. The tensioner bracket MUST be replaced as a COMPLETE unit. Because of damage to the threaded hole during the re-tightening process, the retaining bolt may become loose and cause total loss of the Accessory Drive hence the tensioner bracket MUST be replaced as a COMPLETE unit. Removing and installing the pulley may cause damage resulting in failure. The corresponding workshop manual sections in the Service Literature will be updated accordingly.

24/03/06 Rasping or squeaking noises in the interior
19/2006
There have been various concerns over rasping or squeaking noises in the interior:
1. Creak noise while driving when the front door window is half open.
Cause: Contact between window glass clamp and window glass/window regulator lifting plate. To rectify: Install two new window glass clamps and apply grease everywhere the plastic lifting plate contacts with the rail (vehicles built up to 30.10.2005 (build code 5K) only). For vehicles built from to 31.10.2005 onwards (build code 5K) only grease should be applied everywhere the plastic lifting plate contacts with the rail. 2. Squeak noise from the front door striker area (vehicles built up to 13.05.2005 (build code 5B) only).
Cause: Contact between the front door latch and door striker. To rectify: Adjust the front door latch to the striker. If the concern is still present, install a new front door striker. 3. Rattle and creak noise from the upper rear door striker (vehicles with rear doors built up to 24.12.2005 (build code 5E) only).
Cause: Movement between the rear door latch and the upper striker. To rectify: Adjust the rear door latch to the striker. If the concern is still present, install a new rear door latch. 4. Rattle and creak noise from the rear door striker (vehicles with liftgate only).
Cause: Movement between the rear door latch and the striker. To rectify: Adjust the rear door latch to the striker. 5. Squeak and rattle noise from the tailgate (on both sides) (vehicles built up to 26.05.2005 (build code 5B) only).
Cause: Squeak and rattle noise due to movement of the liftgate caused by side wedges. To rectify: Install new side wedges with new bolts on the left and right side of the liftgate. 6. Squeak noise from the lower A-pillar.
Cause: Squeak noise due to metal to metal touch conditions. To rectify: Rework sheet metal components. 7. Squeak noise from the lower B-pillar (non-sliding door side).
Cause: Squeak noise due to metal to metal touch conditions. To rectify: Rework sheet metal components. 8. Rattle and buzz noise on rough road and when closing front or side door.
Cause: Security shield is moving inside the D-pillar (vehicles with liftgate only). To rectify: Remove the rear lamps and apply sealer between the security shield and the D-pillar sheet metal. 9. Rattle noise on rough road from both sides of the vehicle and when closing front or side door.
Cause: Touch condition between the second row side window glass and the track. To rectify: Apply foam between the second row side window glass and the track.
06/02/06 Additional information for installing a new rear door latch
82/2005
The rear door child safety lock barrel is available immediately as a spare part for servicing purposes. If the rear door child safety lock barrel is damaged, it is no longer necessary to install a new rear door latch.
This TSB contains a service instruction for installing a new power rear door child safety lock barrel and a new rear door latch seal.

28/03/02 Brake hum or judder
24/2002
Should a customer express concern about brake hum or brake judder causing steering wheel vibrations, the probable cause of hum is dirty caliper pistons sticking or binding with the brake pad partially engaged. The probable cause of judder is buckled wheels, incorrect tracking or material build up on the inner face of the discs due to the harder pad material. To rectify this concern, the procedures outlined in this bulletin should be carried out.

28/03/02 Engine idle hang up during gear changes, engine running rough/hesitant, or engine speed undershoots during deceleration to a stop
25/2002
Should a customer express concern of engine idle flare/hang up during gear changes or when coming to a halt, or that the engine is running rough/hesitant and the engine speed undershoots during deceleration to a stop, the probable cause is a corrupt throttle position sensor (TPS) signal due to poor electrical contact at the TPS electrical connector and engine wiring harness electrical connector. This concern should be rectified by installing a new TPS wiring loom and connector and reworking the engine wiring harness electrical connector.


12/10/00 Suspension lock to lock clonk.
123/2000
A touch condition between the top plate and the turret upper surface is possible on full droop which may be noticed when the damper is being removed. This is due to the track being increased so that the damper is no longer sitting at right angles to the turret top surface. By removing a small amount of the turret upper inner surface, the damper rod and top plate are positioned in the centre of the turret hole, and the rubber seat on the top plate is allowed to make contact on droop.

the ICV is the little silver block bolted to the top of the inlet maifold to your right as your looking at the engine from the front. Make sure you get a gasket for it from ford before you re-fit it, to prevent any air leaks :D

try the icv first, its a common problem. They get full of crap and the valve inside doesn't open properly causing bad idleing, give it a clean and see what happens. If then its still bad, look down the tps route :D

To be honest, as the ICV comes into contact with petrol on a day-to-day basis, I'd say it isn't harmed by petrol. White spirit on the other hand is unknown..
Coincidentally my FRP is having problems idling, and a google search threw up this thread which is how I came to be here.
Cleaning the ICV didn't help - revs still drop to zero when idle.

Where's the TPS sensor?

the tps is bolted onto the side of the throttle body. I've drawn a red circle around it :D

What I did was to clean the ICV as discussed and clean the holes on the inlet manifold. I sprayed some Servisol switch cleaner on the electrical connector and put it back together - no difference.

Then I took the connector off the TPS and sprayed Servisol on there too. I saw a label on the TPS housing warning about cleaning it or I would have taken that out too.

Anyway, today it didn't stall and it idles at 900 rpm. So I may have fixed it. :)

glad you were so lucky! we have got this problem with 273 but 8 out of 10 times it wont recover it just cuts out :(
im taking half day off work tomorrow though to take it over to ford as guy on the ramp next to me, his dad is workshop controller there and is gonna check the voltage on IDS for me, see if we can resolve it as ours has had the new overlay harness for the ICV in the past, ive tried a brand new ICV, TPS and MAF so am a bit err stuck. so let us know if yours starting playing up again and ill let you know what we find tomorrow!
