CP's son's Fiesta. (please ask your bloke?)Ok. Cp's son has inherited my father in laws old fiesta which is a bdooly good car. It's a 1993 ?K reg 1.1L, but very low mileage and very nice economical runner until last week when it started stalling and not starting.
Long story short, we replaced the leads, rotor arm, fuel and air filters, checked alternator and battery and then gave in and sent it to the local corner (shed) garage. He could find nothing wrong but the diagnostic bloke visited and said (and I quote) "the throttle body is fu**ed."
Now, I believe it is a carburettor (Weber) but the garage says it is single point injection, whatever the difference is?.
Anyway, Cp's son went to the scrappy and got another one. He cleaned it up, took off the old and fitted the new one. It started first time, but first it sounds nice, smooth and healthy, then the revs go up and down, up and down, then it goes to very high revs.
We wound back the idle sped control screw which makes no difference at all.
What's wrong, please and how do we fix it?

don't suppose the accelerator pedal is a bit sticky is it?
or the cable?

It will be a throttle body, not a weber carb, it is effectively a big injector, and air flow meter.
You have an air leak somewhere. It could possibly be in the pipe form air filter to manifold. Is it connected properly? or leaking?

Hellooo...
The cable and peal linkages are all loose, and tomorrow I'll remove it again and refit using liquid gaskets. Thanks.

Cheers, Ali. Car sorted, it was the main bolts securing the throttle body to the manifold. I used liquid gasket and really cranked them down and now it idles beautifully. Going for a test drive now.

No problems darling!

One slight problem; It idles perfectly but when driving the revs tend to stay high and only slowly return to normal when in neutral. So you come up to a junction, come out of gear and the revs take about 15 seconds or more to drop down to 800 rpm idle tickover. Any ideas?

She was round my house this morning. She did indeed have a bustier on and worked wonders

She was at her beekeeping last night. Then on to avert war in the middle east, save us single handedly from global warming, and avert a terror attack from aliens from the planet fksdlktijggjn.
And then on to her mild mannered secretary job.
I think she asked OH

He has gone out but I will ask when he is back here.

Sounds like the mixture is too rich.
Or
Did the new fuel injector come off of an automatic car because some of them are fitted with a device that holds the throttle open to stop the engine staling. This could be removed for a manual car.

Ta. I'll check later.

Dunno what the old car was, but please ask Ade what the device looks like and where I can find it?...My Haynes Manual is cr*p and no help at all. The lad is in a strop cos his car won't work, CP's retired to a darkened room, the daughter just came in, totally blanked us and went to bed, the dogs eating frogs, and I just want to fix the car. Your (and Ade's help is really really appreciated Ali). Thanks.

The device is fitted just above the throttle linkage. When you rev up the engine, and release the throttle this holds the throttle linkage slightly open, and after a little while allows the linkage to slowly close. This should just unbolt.
It is controlled by vacuum. Most likely, it is the mixture at fault, especially after you mentioned that you have been fiddling with it, previously.
Also check has the oil filler cap got hoses to the air filter, these need to be cleaned as the engine breathes into the air filter, via the filler cap. Check that all vacuum hoses are fitted by insuring you cannot hear a hissing sound, when the engine is running.
Let me know how you get on with these.

I would spray a branded very enviromentally unsound carb cleaner through the air intake whilst keeping the revs high, slow return of revs could be gunk in the throttle body
