What will happen if the Volvo s40 accelerator is broken?

Throttle failure will cause the cylinder to be airtight, the mixed gas will leak, the pressure in the cylinder is not enough, and it is very difficult to ignite (high voltage, that is, the pressure in the cylinder and the compression temperature of the mixed gas can't meet the ignition conditions). In severe cases, the cooler can't touch the car, the combustion is incomplete, the locomotive has no power, and it will also cause fart (the exhaust pipe slams).

Vehicle idling jitter; Cold cars don't strike easily; When idling, the tachometer pointer is unstable (idling is unstable) and so on.
