Mums fiesta (honestly)

that is normal behaviour

They all do that sir :-) Our Puma does exactly the same.

Why? Is it just Ford, or do other car makers do this too?

ford are particularly bad, but all cars do it to some extent, it reduces emissions

It also helps to prevent stalling

And improve gear changing.

(probably due to the lower co levels that cars have to run at now) It first started appearing (that I noticed) on Maestro, montego and metros with SU carbs, they had a damper that stopped the throttle slamming shut the last bit, so it has been in place for close on thirty years. (oh f@@@ I feel old)

I've never seen that in any other car, Ford or other wise. It makes driving it traffic a horrible experience. And surely its wasting fuel doing that? Can you expand on that?

It is a very common behaviour for that vehicle. Just do a google for fiesta revving or somesuch. There are some tricks to improve it, but can you be bothered? It is a cheap car and behaves as such, most people just get used to it.

Several cars do that , not quite to the extent of the fiesta though

So if it is a good thing to do why are not all cars like that? I can easily modify my carb to do that :-)I currently use this to add revs when I switch on a/c that I fitted to my car.

See discussion of this here

Ah, I looked there, but didnt find that. (no fiesta in the title!!!)

Anyway, thats the kind of info I was after. Many thanks.

AC

Odd, it didn't do this when it was new. So I find hard to accept it as normal. I'm gonna work through the suggestions on the site that other guy posted.

Cheers for all the replies though. Appreciated.

This happened to me and the answer was the power steering pressure switch going open circuit.

Thus spake Mrcheerful ( snipped-for-privacy@hotmail.com) unto the assembled multitudes:

How so? If the engine idle speed is 2000 rpm at zero load, surely that means more fuel entering the cylinders than at (say) 800rpm, ergo more exhaust emissions. Or am I missing something here?

Yes. Everybody elses complete inability to see that 2000RPM is wrong. It'ds sure make braking interesting once you got down to 2000RPM.

My first car was a '79 Ford Fiesta. It sure as hell didn't rev to

The Puma does it at about 1400 rpm. I can't tell exactly cos the rev counter is small and doesn't have a decent scale on it. I *think* it only does it when the clutch is down and at very low speed.
