Terzo 333

The g/f's car is a 1.6 16v Escort. She is having major problems with it.

Basically the engine will not idle at the correct revs. Whenever she comes up to a stop, and dips the clutch, the revs won't die down, in fact they get higher. Sometimes "pumping" the clutch helps, but not on all occasions.

Its been to two garages now, and both can't say for sure what the problem is. Before it has to go to the (expensive)Ford garage and be put on their laptop, I was wondering if anyone could shed any light.

Many thanks

I had an identical problem in my rover 214. It didnt happen very often but it did happen more when it was in cold weather.

If i pulled up to a stop it the revs would stay at about 2k, if i dabbed the accelerator, however high the revs went up it would stay there too. It was very odd but i dont have the car anymore so i dont worry about it, i never did find out what caused it, i hope your g/f does.

My rover can R.I.P (Rust in pieces)

Needs plugging in at a dealer

Just had a spate of this at work.

This is notorious on escorts.
Usually a re-flash of the ECU does the trick.
Component faults associated, are: ISCV, Hego sensor, and sometimes ECU

Thanks for the replies.

GTB Limited, what do you mean by a "re flash" and roughly how much would this cost ?

Terzo 333,

Re-flashing, wipes out the exsisting map, reloads with the new/update map. Can only be done with Fords diagnostic gear.

I have no idea of cost, as I work in a plant.
The dealer would probably do this as part of finding the problem (if all else fails).

If the problem occurs "when comming to a stop" it can be a problem with the VSS (vehicle speed sensor). A default feature of the EECIV ECU was to raise idle whilst the car is moving.

How high are the Revs? anything upto about 1200rpm whilst comming to a stop is acceptable on this car (bear in mind your rev clock can misread by a few hundred Rpm)

Although it could be a problem somewhere else that is exaggerating the problem, such as a sluggish Idle control valve or a vacuum leak.

HEGO sensor (in english) - is the O2 or oxygen sensor. I would expect a bad idling, or sluggishness if this fails on this engine.

I did do some extensive diagnostics of a Ford Ka with an extreme case of this problem (it revved up between gearchanges!). Problem turned out to be a faulty reverse switch on the gearbox. But the ECU in a Ka is a far later version than that fitted in Escorts, so I doubt that to be the problem in your case, but without checking myself I cannot confim this.

And in response to the bloke comparing it to a Rover - entirely different car and engine management system mate- All Rovers do that sir!

Usually an idle control valve fault, or possibly the engine temperature sensor (part no 6193368) is very prone to failure causing running problems.

had this on a '97 fiesta, and the problem was caused by the MAF sensor...
