Opel Astra H 2004 1.6 LPG 105hp: Ignition Loss, Coil/Candles/Shaft Position Sensor Replaced

Hello. I have Opel Astre h 2004 1.6 with LPG (105 hp) I have had a problem for two months
With ignition loss. I have already replaced the coil, candles, shaft position sensor and the entire module, i.e. this computer was in regeneration and the problem still appears. No matter if I run on gasoline or LPG. Auto at all terribly muddled but after replacing the shaft position sensor goes like a rocket. A friend had a problem with the car crashing, he said that the flowmeter was to blame. I also read that you need to clear some EGR filter but I don't know if I even have one. thanks for the help in advance

And before all these repairs did someone check the compression pressure? Intake manifold leakproofness?
As you have the Z16XEP designation, the EGR VALVE occurs.

The pressure was measured. Could it be a lambda probe?

Accurate computer diagnosis is best when driving - measuring blocks. Check the injectors will not hurt to clean the egr. LPG installation diagnostics.

So look for fault on the lpg side? I was still thinking about the engine driver.

Provide error codes and descriptions.

This is how it looks with me

You can disconnect the plug from the gas controller, put jumpers in the injection circuit and see.

If gas were a problem, Pb would not have a problem and it doesn't matter what fuel I drive.

What vacuum shows MAP at idle?

I don't know if this is the case but the pressure on the valves shows at level 16

I meant the vacuum in the intake manifold on a hot engine.

I haven't checked it yet. If it escaped somewhere sideways it could also cause the ignition to fall out?

We can delve this topic without end. I don't know when he registers these errors about misfires. You can view in live data with a diagnostic device how and when these ignitions fall out. If, as you say, there is no difference whether it is PB or LPG, then you can skip the fuel system, i.e. fuel pressure, injectors. You changed the candles and the coil so I assume that the spark is checked and it's ok. So giving what is the vacuum in the manifold, what injection time, intake temperature, engine temperature, maybe something more will be known. And this is how we can - maybe a clogged catalyst, maybe a changed camshaft, maybe worn shafts or maybe burned valves etc. etc. If you don't feel tired, give it to a workshop, only to one where after reading the error they will not immediately replace the coils.

Q the question is whether the control module on the engine also has an impact on ignition loss? Something I feel that this regeneration was not done properly.

Hello, I have the same astra as you have for the year, the same problem, loss of bets, these data, probe errors, don't mention anything, no cleaning, neither. Have you resolved the problem by then?

As always with gas supply, the first thing is the top cover and valve clearance to be checked.

Check for yourself if it's better to bring the cost to the mechanic?

Added after 27 [minutes]:

I will mention that when the engine is warm everything is fine works on all cylinders when the engine is cold flashing the check off and start the car the check does not flash but the car walks like a tractor until it warms up.

Hello, I've been fighting this for some time. For me there were more complex problems which I eliminated in turn. The first is cleaning the EGR, by the way I have corrected the gasket leaks from the gas collectors, the next one was the thermostat I had a fault, the next one was the heating circuit of the second probe and now as I start the consumption goes to about 20 liters and the first cylinder falls out. Jakbpostoi politely and warms up, he goes furious. I keep searching ...
