late gas response and flicker shaking

Greetings to all.
When my 307sw 2005 1.6 lpg car is idling, it makes a slight flickering of the pressure at idle throttle, as if the engine is drowning. it gives the gas reaction too late. "The vehicle is also spoiled when eating gas," said one of the craftsman. There is no problem when you take over the vehicle. long path short path performance as it should be. fuel is the same, no increase or decrease. I tried the 1.4 ford fiestas of my brother-in-law the other day, the gas reaction was great, and he reacted immediately. I clearly understood that the gas reaction came late in my vehicle. In fact, my brother-in-law said, "You are accustomed to use this tool according to this late reaction." I took care of myself, really, first I push the gas and wait for its reaction and then bring the clutch to the clutch point.
It also does this problem in both petrol and lpg.

Where do you think this problem originates from?

Spark plugs?
coil?
butterfly throat broken or contaminated?
accelerator pedal position sensor faulty?
worst ECU problem?

These come to my mind.

edit: shaking and reaction delayed at the first press on the gas. Other than that, the vehicle is going normal.

I think of a butterfly calibration

Perhaps it is chronic in the 307s.

I said let's do a butterfly calibration today, thanks to a master, he learned about the subject and learned from the internet that my vehicle did it himself. But I don't know how true.

Sir, I recently opened a topic, I did not get a clear answer to the solution and diagnosis, but the problems sounded similar, if you look at it, I add the link below ...

Actually I am curious about the comments of KOLIVA master.
There is no problem going the vehicle, acceleration is good except for slight delay to gas pressure.
fuel is normal, no increase or decrease.
Could there be a situation with the potentiometer on the butterfly?
Is the same thing as the butterfly position sensor potentiometer?

Also mentioned is the air sensor of the intake manifold.
Waiting for the comments of those who have knowledge ...

My forumdaşlarım,
we replaced filters and oil. lpg filters changed. lpg mapping was done again (calibration)
The lpg master says the coil is weakened. If there is no increase in fuel, a little more, you will change the coil when you show yourself.
There is a very slight lag in the gas now, which is when the gas is pressed at idle. The problem is not felt when the gas is pressed at 2000-3000 cycles.
When LPG gas is pressed at LPG, there is a little delay and detonation, but at high revs, the vehicle attaches to the seat.

Normally, I don't have to worry about driving the vehicle calmly, but when the air conditioner is on and the number of passengers is high, I have to wait a little while on the hill. I have to take off with the hand brake.
I would probably put the maintenance time back on the agenda after 10 thousand km.

Get well with this for now

I had the same problem. When he pressed the gas in LPG and gasoline, he perceived it late, accumulating and detonating on departures. I replaced the lpg injectors today. cut off the pat. I cleaned the throat butterfly and got calibrated. now he takes the gas immediately. the traction was much faster than before. I did not have to pull the hand brake while getting up on the ramps today. I hope it continues this way, I don't have a problem .. Azure 2014-06-19 00:18:03

This problem is likely in your coil ...

I installed the original coil, the problem continued, we realized that it was not from the coil. I understood that I had a test in the industry that it felt a little bit of this problem in gasoline. let me see what i will leave the car on tuesday.

Master, my car is diesel, but the same problem is in me, I don't know who I said, I don't know what I said. I am pulling when I hear gas from listening to the sound of the engine, I stop my feet like a novice in the early draft before the gas comes from the clutch, an annoying situation. What is my throat butterfly?

The same problem happened when I got LPG on my car. It is something that will get better from certain LPG injectors or settings then.
