Mercedes benz c 180 coupe suddenly experienced engine jitter during driving.

Hello! 1, too much carbon deposit in the throttle valve leads to poor intake and jitter.

2. Excessive carbon deposition or scorching of the spark plug leads to poor ignition (it is recommended to replace the spark plug).

3. The carbon deposit in the fuel injector is not well atomized.

4. It is possible that the high-voltage package of a cylinder is broken or the high-voltage line leaks, resulting in cylinder-missing jitter (the cylinder-missing method can be used to judge whether the cylinder is missing).

It is suggested to clean the throttle valve first, check the ignition fuel injection signal and then replace the spark plug, scrape off the carbon deposit in the intake manifold and clean the fuel injection nozzle. If the fault is not solved, the maintenance station will read the data stream and fault code with the computer diagnostic instrument, and then prompt maintenance according to the fault code. Have a nice trip. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
