Opel Vectra C P0301 Misfire: Z22SE LPG Engine, Ignition Loss, Cylinder 1 - Error & Solutions

Here's another problem I'm struggling with. Ignition loss on 1 cylinder. Z22SE + LPG engine.
I have already replaced candles and no improvement.
The situation is so that the error occurs sporadically (once a week sometimes two) about 30 seconds after starting the car in the morning.
When I delete it immediately, it pops up again after a week, sometimes two.
It doesn't pop up on gas at all, or at least it hasn't happened yet.
Specially I went only on gasoline, from one mistake to another for almost 2 weeks.

if the only problem is on gasoline, it is suggested to check the gasoline injector, in some cases, if the error passes with the injection, you have a solution, if not, then checking the installation can be done with gas assembly, something went wrong

The gas installation is out, because I have it for 7 years, and it has never been before. This morning it popped out, I deleted it immediately. Today I did about 50km on gasoline, the car started and extinguished several times and again zero errors. At the same time stood about 9 hours not moved from the morning, so probably at 5 degrees outside it cooled down as after the night.

it is really hard to rule out an ignition coil, in the morning when you start it, it starts on gasoline, unless in emergency mode you would start it on gas, but at these outside temperatures it is a pity for the evaporator

Colleague Golfik-81 writes well first the injection change later the candle and the best compression measurement on the occasion of twisted candles and how it will not help you have to think further

The topic to close was caused by a damaged gasoline injector.
