The Potting Shed

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. Confused
