206+ throat butterfly adaptation?

My 206+ vehicle seems to stop when I start the engine when it's cold, the accelerator pedal touches but does not eat gas and clears in 5-6 seconds. My vehicle is lpg and this happens when using both lpg and gasoline. When I opened it to the service, it was caused by the manifold when I opened the hood and saw that it was lpg lied. He said that you will have a throat butterfly adaptation. Anybody is faced with this situation. What is this adaptation problem ...

As far as I know of the gas wires in the 206's, I think there is at least another problem in my vehicle.

I know that an operation for the brain to record the position of the punch, which adjusts the air passage in the throat butterfly, which it calls adaptation, does not deteriorate on its own if the butterfly is not removed. It is also an easy process for a knowledgeable master, but it is necessary to wait for the engine to be icy.

The butterfly was never dismantled, but I changed the battery, and the terminals were removed and installed. Could it be because of this?
