Seven causes and solutions of automobile jitter

The seven main causes of automobile vibration are: lack of engine cylinder, aging or loosening of engine foot rubber, ignition system problems, unstable oil pressure, unclean air filter, open circuit of high-voltage line and blocked fuel nozzle. Solution: Replace the ignition coil, the machine foot glue, the spark plug, the intake pressure sensor, the air filter and the fuel injector.

The reason why the car feels frustrated when collecting oil is that the throttle device of the car has too much carbon deposit.

The solution is: if there is too much carbon in the accelerator device of the car, it is necessary to go to the 4S shop or repair shop of the car to clean the accelerator in time, which can solve the problem of frustrated oil collection.

Clean up carbon deposits every 20,000 to 40,000 kilometers. Excessive carbon deposition will shorten the life of the engine.

The treatment method of carbon deposit is:

1. Clean the throttle, remove the engine trim cover, remove the throttle, clean it with carburetor cleaner, dry it with cotton cloth, and install it.

2. Clean up the carbon deposit inside the engine, add the cleaning agent inside the engine to the oil port, and replace the oil filter after idling for 10 minutes.
