Ford Mondeo MK3 2.0 Gas Issues: Engine Runs Unevenly on LPG, Shuts Off at Idle

Hello,
Mondeo mk3 2.0 - gas from 150kkm. In the meantime, two valve adjustments and one time (about 15kkm ago) the head removed and the adjustment / renovation of valve seats in a professional plant.

From let's say 3-4 weeks there was a problem with the gas. The engine started to run unevenly on LPG, as if the valves were doing it. However, it works perfectly on gasoline - and since I have experience with an engine with non-closing valves, I practically exclude that it is their fault.

Recently, I had 2 trips on a longer track (about 500 km one route) and it is practically impossible to drive on LPG. The symptoms today are as follows: the engine runs very well when running on petrol - be it cold or hot. After switching to LPG, the slow speed jerks - often when you add the gas quickly for a moment, the engine returns to idle speed. can go out. When you try to return from LPG to PB, the engine works unevenly for up to 10 seconds and only then starts working OK. When I turn off the LPG engine and try to start it in a moment - it can spin a good few seconds to start. Through testing, deduction and consultation, it was found to be an evaporator. I bought a recovery kit. I replaced the membranes, O-rings, etc., I thoroughly washed the entire evaporator with gasoline ...

Symptoms unchanged.

And now, upon reflection, another theory comes to me - damaged LPG injectors. One, for example, is pouring. Against this theory, however, I have the fact that the injectors were replaced less than a year ago. I have not done any tests for damaged (in this case I assume "pouring" injections) ...

I am asking for advice and possibly tips on what you would bet.

best regards
LEEYO

Reading the symptoms, only the injections or their electrical adjustment. In front of the evaporator, I would bet on it, the engine then runs very unevenly, stalls or refuses to start, it may be indicated by the transitional time of uneven work after returning to PB.

You need to connect the gas controller and see how the LPG pressure behaves there.
The fact that the reducer is regenerated does not mean anything, many have seen what went the same as before. You did not mention anything about the LPG pressure setting after regeneration and the map.
What kind of injectors do you have?

I wrote a post that two days ago, but I see something that you can't see. Maybe I didn't click send.
Symptoms on reflection clearly indicated injections. However, I was deceived that about 2 years ago I replaced the entire strip with a new one. The previous one ran about 6 years and did 115kkm. Injection is a magic jet. I am already regenerated - I replaced the springs and pistons in all of them. In one case, the spring was broken. The car returned to normal operation.
best regards
