What is the reason why Ford maverick shakes when it is in neutral?

The most common reason of automobile neutral jitter is that the throttle valve is too dirty or the injector has too much carbon deposit.

When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during the cold start, which leads to the lean mixture during the cold start and makes it difficult to start. In this case, it is easy to run into the car only when the gasoline absorbed by carbon deposits is saturated. After running into the car, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture rich, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after starting. The lower the temperature, the greater the amount of oil required for starting, and the greater the influence of carbon deposition on starting.

Solution: clean the oil circuit, check whether there is carbon deposit in the idle motor, and clean it.
