14 imported Jeep, what's wrong with starting with free light?

The frustration of a car during driving is generally inseparable from the development of motivation and gearbox. The engine consists of an ignition device, an air inlet and an oil injector. It is also the power source of the engine. If the fuel injection is reduced, the air intake is reduced and the ignition is weakened, the power will be insufficient and the engine will feel frustrated.

Reasons for engine retrogression:

1. Engine carbon deposit. As a chronic disease of engine, carbon deposition is an important reason for automobile frustration. Whether it is the carbon deposit in the fuel nozzle, throttle, air intake, combustion chamber, etc., it will cause the frustration of the car. Therefore, effective fuel additives, such as PNF stock solution, clean oil circuit and carbon deposit, must be used regularly. It is recommended to drive the car to a repair shop and clean up the carbon deposit inside the engine item by item.

2. Ignition system failure, such as spark plug, ignition coil, cylinder pipeline leakage, line failure, etc. Spark plugs, ignition coils, etc.

3. The oil circuit is faulty, and the oil supply pressure of the oil circuit is low. The fuel supply pressure in the fuel circuit is the guarantee of fuel atomization, but the fuel supply pressure will be too low due to the blockage of the fuel circuit and the failure of the fuel pump, which will affect the atomization. If the fuel supply is not timely, the vehicle will be frustrated.

4. The sensor works badly or fails. The sensor is the sensory nerve of ECU in the car brain, which can sense effective signals.

If it is a setback caused by gearbox problems, it is recommended to go to a professional repair shop or 4S shop to test the gearbox control system.
