206 burns a lot please help

Friends, I have 99 models of 1.4 gasoline 206 vehicles, but with a 32 lpg lpg, it is only 200 km away. If anyone knows a solution of this, I would be happy if it helps.

Have you cleaned the LPG system?

I just bought the vehicle, I paid the maintenance of the oil filter, but I did not look at the lpg, what control should I have in lpg

Have lpg injectors inspect, replace your filter and most importantly, check for leaks.

Today, I went to LPG, they connected the device to the vehicle and told me it burned in gasoline, normally, the gas value of the computer is 2.50 3.00. It is getting to be, but my vehicle is going to be around 5.25.
