My friends vehicle is 2000 models. There is an atiker line. Almost all revolutions are the same thing, as if the vehicle had previously been exploded between 1000-1500 ~ rpm with a blown-up runner exhaust hole. and it is most likely that the gas works by mixing gasoline because it also runs out of gas when going on gas (disassembling and inserting the gas injectors by taking it into the gas, it acted as if it was not in the gas), and when there was no gas, the car did not go away from time to time. What do you think my problem is about? Which part should I focus on?
