Harley Pan Am can't reach you.

What you want to ask is why Harley Pan Am can't call? There is something wrong with the working conditions of the spark plug and ignition coil.

1, ignition system problems should check the working state of the spark plug and ignition coil. The spark plug is damaged, the car shakes and the refueling is weak. The phenomenon of ignition coil damage is that it does not shake when it is cold started, but shakes when it is hot. The throttle should also be checked regularly.

2. The gasoline oil pressure is unstable, and the pressure state of the fuel supply gauge is abnormally unstable, which will lead to the numerical error of the sensor and lead to the idling jitter of the car body.

3. Poor combustion caused by engine oil problems.
