The most common cause when motivated

- Emphasize the engine throttle response is slow, but with signs of shortness of breath is a sign that the engine lost power.Throttle opening is proportional to the gas pedal and the corresponding suction gas, gasoline is also provided at the appropriate rate for each working state.
Thus a necessary condition for normal engine work, producing enough power to have enough gas and wind. Missing one of two things will weaken air.
The air filter is too dirtyThink about this if often causes driving in dusty environments. Prevent dirt loaded air into the combustion chamber. So the air filter needs cleaning periodically from January 3 to 6 times.
Fuel filter rulesThis is the most common cause of major machinery, engine may even die in the middle, but if stopping time can be restarted.
The pump worn or leaking pressure regulator
ECU controls the amount of fuel in the injector open time. Fuel pressure in the system is stable in the range of 2.0 to 5.8 atm due to the continuous pump and regulator. Low pressure reduces the amount of fuel into the combustion chamber.
Very difficult to damage the fuel pump, the average life expectancy of up to 6 years and often rather unfairly. When replacing the fuel filter, injection pressure remains low, some garages commonly attributed to pump failure and replacement decisions. Indeed many cases by the regulator leaking or safe, no petrol in the tank to create pressure.
Injection pressure ensures fuel into the combustion chamber, but the amount may be lower still required. The reason is that the air flow sensor (MAF) sensor or gas absolute pressure (MAP) response is slow, error signal, the ECU controls the injector open time short.
Spark plug electrodes wear
To fire the perfect place, to create the spark plug and spark healthy right time to ensure maximum combustion pressure is when the piston at top dead center. Bu-gi worn, the gap between two large electrodes, gas air mixture is not burning efficiently reduce power. The gap adjustment should be made according to recommendations of each type of vehicle.
Low compression ratioThis problem usually occurs in car use less oil changes or perennial. During fire expansion, high pressure gas passes through the gap between the piston and the cylinder or between the valves and pressure to make compressor to eliminate piston.
In case of heavy oil into the combustion chamber can dirty spark plug. Oils and dirtier faster. It was heavily damaged need to overhaul, to pinpoint this problem can check by pumping compressed air into the combustion chamber through the spark plug port fitting and measuring pressure drop in the compression stroke (all valves of gas distribution systems are closed).
Traffic exhaust
The catalytic converter reduces emissions of harmful gases into the environment. But using it for a long time to become agents that exhaust pipe. Emissions backlog accumulation in the pipe, the engine takes more energy to push them out. Large discharge pressure reduces gas load cause a power loss.
