Yesterday technician on Ford service after diagnostics and other stuff said that I need to change idle valve and ignition coil. And he said that 90% problem in that. OK, both was changed, but today at morning the same nuts was repeated  Computer diagnostic of engine shows errors only on lambda-sensor, but I have normal fuel consumption and it's not related to morning problems, I think. 
One more time about my problem: when engine is totally cold it's started up, but can't hold xx, I need to help with throttle. Maybe during first ~1min engine works on few cylinders, flapping and coughing when I press accelerator, but even if I press it and see that revs ~1.5K, power on wheels going abruptly, maybe in 1-2 sec after I press accelerator. Then, after about minute of that, engine works fine and smooth all the time until next totally cold of it.

Guys, what do you think about air leak-in? Sneezing and coughing from exhaust and throttle collapse on low revs are caused by poor mix, aren't it? So I think extra air could leak in system, but through what and how can I check that?
Cause logically, when engine little warm, some gasket enlarges and pass much less of extra air in cylinder, no?

hi there
check all the pipe work for the erg valve to the rear of your 24v engine.

Don't understand how can I check the pipe?  It's metal, right? So, what weird I can see there?

Thanks, very interesting and I think related to my problem, but why this pipe leaks only on cold and only on idle revs?
Also, can I be sure that problem in EGR if I disconnect the multiplug to pressure transducer like it was described here? http://www.fordscorpio.co.uk/faults_misfire2.htm

hi there
the issue will be worse when cold because the fuelling will be at it's richest at start up.
sometimes a DTC will come up when you disable the egr. i never got one when i blanked off mine for a while.
can you what your long term fuel trims are? this would give a good indication.

Sorry, maybe it's may bad english, but I don't understand what DTC is? And how about disconnect that multiplug from pressure transducer? It may helps with diagnostic of EGR problem or not?
And sorry, but what do you mean saying

OK, it's over. Engine not starting anymore. Not even fires when I engage starter. 
How about injectors? Old LPG system was installed and used before me. Can it helped to finish off my injectors? And where I can find specifications of Cossy injectors? Cause genuine is unjustified expensive.

Motor-mechanic look on my Cossy today. First, he checked some pulses on ignition coil connector and said that that pulses goes not well when I crank the starter (I just don't remember what wrong with them  ). Then, we take out high voltage wire, put old spark plug in and check the spark when I crank starter. It was very faded, as the man said. Then we screw out new spark from the engine - it was totally black and all in fuel. So, problem not in the fuel system, right?
Weak spark and not normal pulses on ignition coil. What should I check now? Ignition coil was changed - no effect, so I think it's in normal condition.

EDIS pack inside the front wing could be the problem worth checking. but others will know more than me.

hi there
iirc, the edis pack is on/at the coil pack on the 24v.

And what controls the spark on 24V? Only PCM? Or between PCM and ignition coil there is something more?

hi there
yes, the EDIS pack. 
on the 16v engines, it was on the inner wing, but as i said, on the 24v it's at/on the coilpack.
i will have a big multiplug on it.

Also, installed old dry spark plugs just now - engine starts with easily, revs was on 1.1K few seconds, then few seconds on normal ~800, then, like before - engine dies.

hi there
it sounds like you're in limp home mode. is your fuel pump running all the time when you switch on the ignition?
iirc, it will. that would explain the wet plugs.

Don't know, cause I don't hear working of fuel pump, even in full silence after I just turn ignition "ON". And wet plugs, I think, because I crank my starter many times without firing.

I'm in confusion. Other mechanic said after listening my story, that problem in scale in compression chambers or on valves, besides old LPG may point to that. And after all, my Cossy have almost 400K km of mileage, so it really may be true. What do you think guys?
