车型:配置1.2L发动机。行驶里程:60000km。故障现象:车辆行驶中加速无力,加速至2500r/min发动机转速很难提升,急加速后松加速踏板时发动机熄火,缓加速缓松加速踏板时则不会熄火。故障诊断:维修人员清洗节气门,更换MAP,打吊瓶,更换EGR阀,拆检三元催化器未见堵塞,测量燃油压力正常,经过上述维修故障未排
Model: Configuration 1.2L engine. Mileage: 60000km. Symptom: Vehicle speeding weakness, accelerating to 2500r / min engine speed is difficult to enhance the rapid acceleration after the accelerator pedal when the engine stalls, slow acceleration when accelerating the accelerator pedal will not turn off. Troubleshooting: maintenance personnel to clean the throttle, replace the MAP, hit the bottle, replace the EGR valve, dismantling the three-way catalytic converter is not blocked, measuring the fuel pressure is normal, after the above maintenance failure is not row
