Hello friends. My 2004 model 1.4 car has an atiker lpg. The system followed in 2011 has been around for 1 year and we did not solve the problem. When the car is started when it is cold, it stops the car with a big shock during the park. They said that the throat butterfly was cleaned and worked properly for 2 days. 3. Gun cancellation. The spark plugs were replaced with LPG injectors, and it was able to last for 2 days. As you move to the gas on the move, the hard night is like pulling the car from behind 1 to 2 seconds. I am waiting for your suggestions.
