Geely Jiaji has a weak acceleration.

The main reasons for weak acceleration are that the mixture is too thin, the ignition is too late or the spark is weak.

The specific reasons are as follows: ① Air leakage in the intake pipe causes the mixture to be too thin. ② The fuel pressure is low, and the fuel injector and fuel filter are blocked, resulting in less fuel injection or slow fuel increase. ③ The signals of air flow meter, intake manifold absolute pressure sensor and throttle position sensor are abnormal, resulting in no or little increase in fuel injection. (4) Abnormal sensor signal leads to inaccurate ignition timing and delayed ignition. ⑤ Poor spark plug, igniter or high-voltage line leads to weak high-voltage spark ⑤ Dirty throttle body. ⑦ The exhaust gas recirculation system is not working properly. 8 The exhaust pipe is blocked. Pet-name ruby cylinder pressure is low. Attending turbocharging system failure.
