Misfire and stop problem when the engine is cold?

My 206+ vehicle is lpg and when I start the car in the morning, it kicks 5-6m without going, it feels like it will stop and when the gas is given, the accelerator pedal is not up to the cross, but it does not eat gas, it clears in 3-4 seconds and it does not have any problem in its departure and traction. This is what I said before it goes to the gas tube, i.e. it is in gasoline.

nobody knows the answer to this yet. let me not say all but this is the case with most lpg pejo. manifolt is completely made up, though it does at lpg. Do not believe in services, most ignorant torpedo men work there. There are people under the name of master who do not know how to adjust brakes even more. It is a pity for the money given to them. If we go back to the subject, the situation is like yours and I don't wear it too, the engine is getting better when it gets hot, I think you get used to it and don't let it get messed up and keep your money in your pocket

This situation bothers me, but the master who had the LPG said that I would have no problems. I am very pleased with this car out of this problem and looked clean, but I am thinking of selling it just because of that. I had no problems for a year, the service said it was entirely due to LPG and I should have it disassembled :(
