13 causes of jitter in the third gear of sourato.

13 Souranto third gear jitter causes are as follows:

1. The throttle valve is too dirty or the fuel injector has too much carbon deposit: when the engine has too much carbon deposit, the gasoline sprayed by the fuel injector will be absorbed by a large amount of carbon deposit during the cold start, resulting in too lean mixture during the cold start and difficult start.

2. Ignition system problems: Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to such failures.
