What are the reasons for the lack of power in the acceleration of the Delong X3000?

The following are the related reasons for the lack of power in the acceleration of the Delong X3000: 1. Excessive engine water temperature: There are many reasons that can cause the engine water temperature to be too high or even "boil over," such as damage to electronic components in the cooling system (thermostat, cooling fan), poor radiator performance, insufficient coolant, etc. 2. Pull over but do not turn off the engine: Pull over, but do not turn off the engine immediately! Because the coolant temperature is already very high, and its cooling capacity has reached its limit. If the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft). 3. Electric water pump: Of course, if the engine has an electric water pump, it will be better. If the excessively high temperature is not cooled, the engine will still struggle. If you let the engine idle for a while, the continuously circulating coolant can still reduce the impact of high temperature on the engine. 4. Check the antifreeze: Check if there is a lack of antifreeze, which can cause the engine water temperature to rise. Also, check the circulation of the coolant to see if it is not flowing properly. Additionally, you can check the water temperature sensor, water pump, thermostat, cooling fan, etc., as these can all cause the water temperature to rise. If you are not very skilled, it is better to go to a repair shop for inspection.
I've seen the issue of the Delong X3000 lacking acceleration quite a few times, and it's mostly related to engine problems. If the fuel system isn't working properly—like the fuel pump failing to supply enough fuel or the injectors being clogged—the engine won't get enough fuel and feels sluggish. When the air filter is too dirty, insufficient air intake makes the car struggle to breathe, especially when climbing hills. Sensors can also be troublesome; for example, a faulty oxygen sensor sends incorrect signals to the ECU, messing up the air-fuel mixture. If the catalytic converter in the exhaust system gets clogged, exhaust pressure can't escape, causing acceleration to stall. Worn-out spark plugs can lead to weak ignition or even engine failure. These parts need regular checks. I recommend scanning for trouble codes with a diagnostic tool ASAP—don’t wait until the engine overheats or blows up to take action, as that’ll save both money and hassle. If you're doing it yourself, replacing the air filter or spark plugs isn’t expensive—start with smaller components before jumping into a full engine overhaul.
