The standard model of the Great Wall Gun sometimes has a high speed, but what is the reason why the car doesn't go?

The standard mode of the Great Wall Gun sometimes has a high speed, but the car may not run because of insufficient oil pressure or blocked throttle, or it may be because of blocked throttle. The specific reason is to go to after-sales maintenance. The speed went up, but the speed couldn't. Maybe the oil pressure is not enough, so the oil pump of the car doesn't work well. You can check whether the oil filter or oil nozzle is blocked. If the car can't accelerate, you can also start from the clutch part. If the clutch partially fails, the speed will not go up. If the throttle is partially stuck or the stepping motor fails, the speed will not go up. It can also be ruled out whether the exhaust part is blocked. There is also whether the circuit is short-circuited or open-circuited, and whether it is connected properly. Emphasis is placed on parts that are easy to wear, such as ignition coils and spark plugs. After stepping on the accelerator, the speed is very high, but the speed can't get up. There are many reasons, which need to be checked one by one. It is best to go to a special maintenance station for investigation.
