Dear all, just after refilling my tank today, I went on road and when going from 3rd gear to 4th I got a stall and the engine stopped. Then I stopped at right and started it again. First few times it wasn't able to stay still at idle and the engine stopped. When I press the gas excessively it was able to go on with some shake but still was not normal. After 50 km with intense fuel consumption and 3rd and 4th gear it was able to stand in idle but not in the first usual high RPM it was. It stays in about 800 rpm which was about 1000 before. The thing is i recently brought it and don't have too much to spend. Do you have an idea guys what kind of a trouble I am facing with? Thanks in advance.
