Anonymous users2024-02-15Hello! Please check if there is any weakness caused by the lack of cylinders or poor working of the engine!
Check whether the ignition system is normal, check whether the spark plug gap is too large, and check whether the throttle and intake pipe and fuel injector have too much carbon deposit!
Check the ignition coil or cylinder wire for leakage!
Check if the gasoline pressure is normal!
Check the clutch plates for burnout!!
I hope it can help you, and I wish you a happy car! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Anonymous users2024-02-14Hello, the main reasons here are as follows: first, the fuel pressure is too low, resulting in insufficient fuel supply and insufficient power, it is recommended to clean the injector and check the oil pressure at the same time. Second, if the ignition is not good, resulting in poor combustion, and at the same time obvious waste fuel, it is recommended that you replace the spark plug.
Third, the engine throttle valve is too dirty to clean and exhaust the three-way catalytic converter is prone to failure. It is recommended that you go to the repair shop for a full inspection. I hope mine can help you and have a nice ride.

Anonymous users2024-02-12Please consult the gods, what should I do if the speed of Weizhi V5 is weak, please consult the gods, Weizhi V5 ( Check the transaction price |What to do if the acceleration is weak The acceleration weakness of the car sometimes appears in daily use, and sometimes after maintenance. Acceleration weakness is generally a problem during ignition and fuel injection, the most likely of which is that there is a problem with the storm sensor, the computer can not give the car a proper data, and can only work according to a fixed program at the moment, so it will accelerate weakly. In addition, too much oil or bad oil can also lead to poor refueling.
In short, the spark plug gap is large, the cylinder line has a leakage place, the three-way catalytic is blocked, the nozzle and throttle have more carbon deposit, or there is a problem with the circuit, there is a problem with the oil pump, and the gasoline grid is a little dirty, which will lead to weak acceleration. So the following checks are performed. One is to check whether the intake pipe is leaking.
The second is to check whether the ignition time is too late. The third is to call up the fault code and analyze the cause of the failure. Fourth, check the fuel injection system, such as fuel pressure and injector work.
Fifth, check whether the ignition system, especially the storm sensing bucket resistance device and igniter, are working normally. Sixth, check whether the throttle position sensor is normal. Seventh, check the working conditions of EFI circuits and components related to fuel injection.
Finally, check the cylinder pressure, valve clearance, and spark plug operation. 1. In the case of weak acceleration of the car, turn off the engine first and check whether the oil volume of your empty mountain car is enough, if there is more or less, you need to pay attention, more or less oil will cause the car to accelerate weakly. If you have less oil, you can add some by yourself.
If you have more, go to the repair shop and let them help you deal with it. 2. Think about how long your car has not been maintained, the general throttle valve needs to be cleaned for 20,000 kilometers, the fuel injector is basically 2 to 30,000 kilometers and needs to be cleaned once, the spark plug is basically 40,000 kilometers and needs to be replaced, and the three-way catalytic converter can be cleaned for about 20,000 kilometers. The above throttle, fuel injector, spark plug, and three-way catalytic converter are cleaned and replaced to remove carbon deposits, and there is also to improve ignition.
3. The fuel pressure and cylinder pressure lead to acceleration weakness, and the cylinder pressure must be checked with the help of detection tools, directly start the engine to make the temperature of the car engine directly reach the normal temperature, and then remove the spark plug and put the inspection head in. Then turn the engine on and let it rpm at 100 to 150 rpm, and turn off the ignition in about 5 seconds. At this time, the pointer on the meter will gradually rise to a certain moment and stop, and the pressure at this time is the cylinder pressure.
The fuel pressure check needs to be prepared in advance, the fuel fuse must be unplugged, and then the oil pipe is disconnected, the fuel pressure gauge is connected, the engine is hit, and then the fuel pressure can be read out. @2019
Key features of Weizhi:
1. The engine Toyota is fuel-efficient and powerful, and it can be compared with some of them. The engine technology is mature. >>>More
The engine is the same as the N5, but the vehicle space is much larger than the N5, and the interior of the car also has the feeling of a mid-range car, which is divided into manual automatic integration and five-speed transmission.
I think, or King Kong good, this is just a personal preference difference, I bought the Freedom Ship in 07, at that time there was no impression of King Kong, once in 4S maintenance, change the oil, there is a King Kong on the side, let me not expect it, when the car was on fire, not a lie, that is in the house, very surprised me, since then I have been a little concerned, and then drove once, the best impression to me is silent, comparable to Japanese cars, and the space is also good, the power can be considered okay, It's enough for your own use, and Geely's accessories are very cheap. Weizhi, I think**It's a little higher, the workmanship is OK, but Xiali changed a shell, it's so expensive, I don't think it's worth it, as for the friends of BYD mentioned above, I personally think that BYD's marketing is first-class, but the car, it's really hard to say, it may also be some comments on the Internet, **gave me a misunderstanding, I won't comment. However, buddy, if you buy a Geely car, you have to be prepared, many people think that Geely is not a good car, and often meet people who look at the car from afar and say: >>>More
The actual fuel consumption is still a little less saved, this car is also more practical, the sedan Weizhi is cost-effective, but after all, it is a new car, and it has not been fully tempered by the market, in addition, I think there is a big problem with the positioning of the sedan Weizhi, and the difference of 10,000 yuan between the hatchback models is not worth it, you look at the Weizhi of the hatchback, it may be more suitable, or choose Wilo directly, which is more mature and practical.
Weizhi is an enlarged version of Xiali, with a large space for fuel saving, and there are more problems in other aspects, so it is better to buy Weilo. >>>More
