What is the reason why Lincoln mkc suddenly crosses the line during normal driving?

1. Too much carbon deposit in the engine causes the vehicle to shake when driving. Most of them are due to the serious carbon deposition in throttle or fuel nozzle, which will make the combustion mixture thin and thick for a period of time;

2. Spark plugs and ignition coils are vulnerable parts. If the performance of the spark plug decreases or the vehicle uses a spark plug with poor quality, it will cause the vehicle to shake;

This engine is short of cylinders. If the cylinder doesn't work normally, and part of the mixture is not fully burned, the exhaust pipe will explode and shake.

4. If there is a problem with the oil supply pressure of the oil pump or the intake pressure sensor fails, the error of data transmission will also make the vehicle tremble.
