When Li Xia's fourth and third fuel trucks don't speed up, the fuel pressure is too low, what is the reason for the air intake system leakage?
2. Troubleshooting steps: 1. Whether the "Check Engine" warning light goes out after the engine is started. 2. 1 If the warning light does not go out, check the cause and location of the fault according to the fault code. 2.2 The warning light goes out, and check the oil pressure of the supply system, the working condition of the injector and the gasoline quality. 3. Check whether the ignition timing is delayed too much. 4. 1 Ignition timing is normal. 4.2 ignition timing delay is too large. Check whether the knock sensor and ECU are normal. 5. Check whether the EGR system is normal. 6. Check whether the air intake and exhaust system is blocked. 7. Check whether the signals of air flow meter, throttle position sensor, crankshaft position sensor, camshaft position sensor and oxygen sensor are normal. 8. 1 is not normal, check the sensor fault. 8.2 Normal, check ignition high pressure and ignition energy when accelerating. 9. 1 If the ignition high voltage and ignition energy are abnormal, make fault diagnosis according to the ignition system. 9.2 Ignition high pressure and ignition energy are normal. Check ignition timing, cylinder pressure and engine mechanical failure.
There are three reasons for this problem: first, the mechanical device of the accelerator pedal is stuck; Second, the throttle cable may be deformed and stuck; Third, too much carbon deposit in the throttle causes poor acceleration effect; If you buy a new car, there will generally be no problems elsewhere. It may be that the high-speed gearbox is not suitable for this engine and the power transmission connection is not good.
