20 10 crv2.0 two-wheel drive now 60 yards later, the reason why the accelerator can't accelerate and decelerate.

It is recommended to check the following reasons:

First of all, the vehicle engine is unstable or unable to accelerate due to carbon deposition. In this case, it is recommended to clean up the carbon deposits in the throttle and air intake, and then check whether the carbon deposits in the cylinder and the valve seat are serious.

Second, the engine ignition system failure is generally caused by the aging of the ignition coil or spark plug. Therefore, it is enough to replace the damaged ignition coil or spark plug.

Third, the engine fuel system is faulty, the oil circuit is too dirty, or the fuel quality is too poor. It is suggested to clean the oil circuit and add some high-grade gasoline or fuel treasure.

The last case is considered to be caused by the problem of the vehicle gearbox. The friction plate inside the gearbox is worn, or the solenoid valve body is damaged, and the upshift is not timely or the speed is weak. Need to check the gearbox.
