First of all, your new vehicle is good. I wish you could use it without any accident. If you remember incorrectly, I hope your vti engine would be your vti engine. lpg distressed in vti engines. there are fine details extending the injector hoses etc. into the manifold. If it is not in order, it is really hard to set it up, it looks at a good lpg master, but in general, the lpg system can be completely overhauled or it may have to be installed from scratch. First of all, my advice is to use 100-150 km gasoline, turn off the LPG system completely, get the gas map smooth, then the LPG setting becomes smoother. Follow the gasoline, do you have the same problems.
