You can google for a better explanation, but if you waft some flammable
gas in the vicinity of an air leak, it richens the mixture & the revs rise.

Presumably that only works for leaks when it's sucking and in the intake
system?

It was the throttle body housing that needed cleaning, they sprayed some
sort of carb cleaner into the housing mouth and the engine is now
running perfectly smooth.
Thanks for all the help trying to sort this out for me.

The vehicle has been fitted with a replacement Zetec engine which has
apparently only done 55,000 from new but I'm having major problems with
the engine missing, when I say missing I mean when you put your foot
down to accelerate (in any gear) it hesitates to the point of it almost
stalling and I have to change down a gear before it picks up again and
then it goes like a rocket, pumping the accelerator pedal does nothing.
So far I've fitted a secondhand gearbox, new clutch, new front discs,
pads, wheel cylinders and brake shoes, rear brake pipes, n/s wishbone,
two tyres, rear exhaust, battery, oil and filter, air filter, new plugs
and a Lambda sensor.
There appears to be no end of cost ;(
The last straw was when I took the vehicle to a garage who apparently
had engine diagnostic equipment and they said it was the "air flow
sensor", they charged me 47 quid labour for the diagnosis and for
cleaning the air flow sensor element.
After the element was cleaned the engine did run better but it still
hesitated occasionally on acceleration and they advised me to replace
the air flow sensor if the problem persists (which it did). So the
following day being fed up with it still missing I bought a new air flow
sensor which cost nearly 150 quid including vat.
But even with this new air flow sensor the engine is showing exactly the
same symptoms by hesitating when putting demand on the accelerator.
The problem I have now is finding a reliable garage to correctly
identify/diagnose the problem.
Is this a common problem on Zetec engines?
Should I take the vehicle to a main Ford dealer in the hope that they
might be able to correctly diagnose the fault?
Has the fault been missdiagnosed?
Is the new sensor likely to be faulty or could it be something else?
I don't mind paying for a decent service but feel as though yet another
garage is out to fleece me.

To be honest, it's a common fault with all engines. I think there's an
airleak somewhere, upstream of the air flow meter. A split vacuum hose,
cracked inlet pipe or leaking inlet manifold gasket will cause this. The
fact the engine's been replaced may also contribute to the possibility of
damage to pipework. Check pipework in the engine bay, listen for hissing
etc. Inlet pipe, inlet manifold, brake servo pipe, breather pipes etc.
Also, common faults on these engines are HT lead breakdown due to
incorrectly gapped plugs. Can't remember the exact gapping (confident Tim...
can advise), but replace the plugs with those of the correct gap, and HT
leads with good quality Ford items (cheaper pattern leads get eaten within
miles due to high HT voltage). Change the oil for a quality semi synthetic
5w30 oil to prevent valves sticking (which may also be the root cause of
your problem).

Other than the MAF, there's nothing really that would cause the engine to
exhibit that sort of behaviour.

It's an 1800 Zetec engine, I'm sure we're capable of sorting it for him here

I'd go with the HT leads and then the coil pack. You would think that a

HT Leads are a consumable item on this engine. What leads are fitted, how
long have they been there, what condition are the plugs in, and is the coil
pack surface clean??
I would put money on a set of plugs and Genuine HT leads will immediately
solve your problem!

I'd not thought to inspect the hoses/pipework etc,
I'll check this out on my day off, as always its a process of
elimination, unfortunately for me the enging is complicated compared
to a normal petrol engine when it come to fault diagnosis.
There doesn't seem to be a very good fit from the "Throttle Housing" to
the plastic air filter assembly that is bolted across the rocker cover,
I would have though some sort of a gasket should be fitted at this point
to fix the gap.
I've got the engine oil but not put it in yet (weekend job).
I've fitted new plugs and they're gaped at 1.5mm IIRC.
I'll replace the HT leads (with Ford ones) and see if that makes a
difference.
Thanks ;)

I expected the garage to pick-up on a faulty sensor, they admitted to
disconnecting and reconnecting the air flow sensor to diagnose the
fault, not exactly plugging it in to a diagnostic machine which is what
I thought I was paying for, but I get the impression they've done the
diagnosis by trial and error ;(

I've been in and out of this group for years and always though it to be
a none 17 year old newsgroup with very knowledgeable people, I am
confident the answer to my engine problem can be solved in here ;)

The Zetec engine has been around for a few years now and although it is
new to me it is not new to others who have had more experience than me
identifying engine problems, I hope to draw on peoples experiences
of this particular engine which should help me to eventually elliminate
the fault.
There has been very sensible suggestions so far ;)

Well I did say at the start of my post, the car was given to me, which
is why I don't mind spending a certain amount of cash on it, but I am
disappointed to find I still have a major fault after spending close on
600 quid on it so far. The car is not worth the ammount I've spent on it
and I have only continued to splash out because it is a GHIA which has
all the extras fitted as standard.

Did you replace the plugs & leads with Ford ones, and set the gap to
1.0mm? The 2.0 engine has a well known mis-fire problem at high load.
Your problem sounds far worse than that one though!

Not yet, I've only replaced the plugs so far, my days off are Monday and
Tuesday so I'll have a go at most obvious then and report back here.

Update:
I've fitted brand new Ford HT leads, changed the engine oil with the
correct semi-synthetic stuff and although the spark plugs were new I've
replaced them with new Ford ones and gapped them to 1.0mm.
The engine definitely runs better than it did, but very occasionally it
still has the tendancy to hesitate slightly when accelerating, though
more like you would expect from a very cold engine.
However last night the hesitancy reappeared again quite severe, only
this time from start with a cold engine, although it did improve as the
engine warmed up but I had to wait at the side of the road for a minute.
I have tried to check the hoses for leaks but to the best of my ability
I can't see or hear any leaking air etc.
I think my next job will be to perhaps change the fuel filter, seeing as
the old oil filter was beginning to go rusty as the rim would suggest it
was really old so I expect the fuel filter to be just as old if not
older and I believe this could cause the intermittent hesitation.
Any further thoughts gratefully received.
Steve.
