First of all, welcome to us. Use your vehicle on a 150-250 km gasoline, hojam. if it continues, replace the spark plug. the worst possibility is that the catalyst is full. When was lpg installed, how many kms of the vehicle was used.

I did it, I did everything you called my teacher, I used 500 km gasoline, I changed the spark plugs, I have canceled the curve, including the coils, 8 years ago.

Hello, as mentioned, you may also have a problem with burning. There are sensors before and after the catalyst. These ecu either inform or turn on the malfunction lamp. This malfunction may also be due to burning problem, even if the catalyst has lost its process. Check out the article in the link below. You know your vehicle better. I hope you find a solution accordingly.

thank you so much
