My Acura CDX has been driving for 5 years and almost 87,000 kilometers, and recently there has been a serious engine shake, and the throttle is slightly vibrating (very subtle but can be felt)
The reason for the problem with the vehicle is not because of the car itself, the reason I put it in the summary there
The GIF diagram reduces this vibration
The dashboard also appears with a bunch of code hints
Engine failure, steering wheel, ESP, hill assist
The same is true of speeding up
The first throttle generation is very weak, from 0-20, 20-40 this generation is very strenuous, the speed of the pull is very high, often to 3000 rpm before about 2000-2500 rpm can be
Originally in 80,000 kilometers when there was this problem, take to the 4S shop test said to change the injector nozzle to 5, 6000, at that time said that the fuel injector is a little blocked, and then there is carbon deposit? Anyway, I went there because I had to do small maintenance, and I didn't care much about these fault lights on the dashboard at that time. Thinking that there was carbon deposit, I bought a fuel treasure and used it, and then ran at a high speed and pulled a high speed.
This is to see netizens say that the fuel treasure professional brand, when used to run high speed is a little better, but then still feel that the throttle first generation is not effective
The middle paragraph occurred during the period of 80,000 to 87,000 kilometers, after running 7,000 kilometers, parking the car in the car and charging the mobile phone, and then there was a lot of instrument failure at the beginning of the article, it was still in the field, fortunately, it was still a smooth drive home.
Then still pull the car to the 4S shop to do small maintenance, and then ask the fault code of the dashboard (the 4S shop did not eliminate the fault code, because the parts did not replace the fault will not disappear, even if the code is eliminated The problem of the car is still there) What is going on, the answer is still because of the injectors These problems, I want to go outside first to do a nozzle cleaning and fault detection.
The next day, I took the car to the Tuhu to test what the problem was
What is more funny is that this detection master came up to the computer detection brand is "Chang'an", I said to him a few times this is not "Chang'an" is "Acura", "Acura" is "Honda", you can order Honda's, only successfully tested (later learned that this master is specialized in Audi)
The preliminary test result is the lack of fire in the No. 1 and No. 4 cylinders, I want to do the cleaning of the fuel injector and the throttle, the master wants to do it with the small maintenance, the result is that my small maintenance has just been done, the master said that the next time, the detection computer ran again, the fault code was eliminated, but the problem of the car still exists.
After that, I bought the fuel injector (no-demolition) and the throttle cleaner and fuel treasure on the Internet, or thought about whether I could rescue it, and went to a shop under the Line of the Beijing Car Association to test, the testing master looked at it and felt that this fuel injector was not easy to get, and it was not necessarily good to make it, and it was recommended not to toss
In the end, there was no way to open a 4S shop to replace the fuel injectors and spark plugs
This is the old spark plug a total of four, of which 2 colors are very red, 4S shop said that this is not normal problem
This is the replacement of the injector and spark plug
The maintenance took a total of 3 hours duo a little bar, the cost is 6860 yuan.
After the replacement, the whole machine is normal
This is the acceleration situation (see the speed and code table)
summary
I probably know why my car is having this problem, because it was always good until a few times after adding oil sold by individuals. The car itself is equipped with No. 95 gasoline, which is a little more expensive than the 92, and the oil sold by individuals is much cheaper than the gasoline of the gas station 92. Some cars may have no problems with it, but different brands of car engine technology are different (including whether your vehicle is naturally aspirated or with a turbine, your vehicle itself plus 92 or 95 and other factors are related) so my one appeared this situation, and finally spent nearly 7,000 yuan to solve, I did not add several personal sales of fuel to save to see if there is a hundred yuan, and finally spent so much money as a tuition fee.
Finally, go to the gas station to refuel with confidence
So in the end, I strongly recommend that you go to the gas station to refuel! Or your car use scenarios and conditions are convenient to consider new energy vehicles.
I also recently purchased a BYD Song PLUS EV at home, which is also the first time I have used a new energy vehicle.
