How to solve the idle intermittent jitter of Cruze hot car

There are many reasons for the intermittent idling jitter of Cruze hot car in Pacific Auto Network, which may be the serious carbon deposition in the engine and the failure of the ignition system. Check whether the idle motor has carbon deposits to be cleaned, check the working conditions of spark plugs, high-voltage lines and ignition coils, and replace the spark plugs.

1. Too dirty throttle or too much carbon deposit in injector are the most common causes of engine jitter. After the car has been driving for a period of time, the dirty throttle will cause the throttle to close loosely or the idle stepper motor to get stuck, which will lead to the high idle speed of the engine. The carbon deposit produced by the engine during the working process will also cause the vehicle to shake, especially when the vehicle is started, the engine shake will be more serious than normal, and sometimes it will even fail to start once. Solution: Clean the oil circuit and check whether there is carbon deposit in the idle motor to be cleaned.

2. Ignition system failure, spark plug, high-voltage line and ignition coil will not work well after working for a certain period of time. Solution: Check the working conditions of spark plug, high-voltage wire and ignition coil, and replace the spark plug.
