#1 车停着等红绿灯的时候,会忽然轻微哆嗦一下
车停着等红绿灯的时候,会忽然轻微哆嗦一下,我看那个表大概从1.5掉到0.5去了
就哆嗦那么一下,以前没有,怪怪的。KIA SPORTAGE 2018开了12万了

积炭,常见问题,无解
我怎么感觉是TRANSMISSION的问题,这个车加速不好,0-40很慢,40-60还可以
要是TRANSMISSION坏掉就惨了,我指望它开到16万迈呢
那是空调启动了,你把空调关了就没事了。
车停着关tranny什么事
空调关了也不行,AI说是throttle valves/body脏了
啥地方积碳?Mass air sensor? o2 senser? 火花塞?
AI这样说
Common Causes:
Worn Engine Mounts:
.
These mounts secure the engine and absorb vibrations; when they fail, you'll feel the engine's vibrations throughout the car.
Engine Misfire:
.
This occurs when a cylinder fails to ignite properly, often due to worn spark plugs, a bad ignition coil, or a dirty fuel injector.
Vacuum Leaks:
.
A vacuum leak introduces extra air into the engine, disrupting the air-to-fuel ratio and causing a rough idle.
Fuel System Problems:
.
Clogged fuel injectors, a weak fuel pump, or a clogged fuel filter can all lead to an inconsistent fuel supply and rough idling.
Dirty Air Filter:
.
A clogged air filter restricts airflow to the engine, which can disrupt the combustion process and cause shaking.
Less Common Causes:
Faulty Throttle Body:
.
A dirty or malfunctioning throttle body can disrupt airflow to the engine, causing vibrations.
Bad Oxygen Sensor:
.
The oxygen sensor helps regulate the air-fuel mixture; a faulty one can lead to poor combustion.
Catalytic Converter Issues:
.
A clogged or damaged catalytic converter can restrict exhaust flow, causing engine vibrations and performance issues.
Faulty Alternator:
.
An inconsistent electrical supply from a failing alternator can sometimes cause engine vibrations at idle.
What You Can Do:
Scan for Codes:
If your check engine light is on, use an OBD-II scanner to retrieve diagnostic trouble codes, which can help pinpoint the problem.
Inspect Hoses:
Look for any loose, cracked, or disconnected vacuum or air hoses under the hood.
Visit a Mechanic:
If you're not comfortable diagnosing and repairing the issue yourself, a qualified mechanic can accurately identify the cause of the shaking and perform the necessary repairs.
这么复杂,就忽然哆嗦一下就好了,看来我只能默默承受了,
我老板的FORD FOCUS哆嗦得才厉害呢,跟筛糠得一样
我这个忽然晃一下,看来不好说是什么
这就对了,怎么脏?就是汽油不完全燃烧,部分汽油碳化聚集在那里
上次我跟DEALER说,他们没说什么,烧机油他们说是PISTON RING
磨损,也不知道哪里碳累积了,我买了几桶chevron fuel system cleaner
看看是不是管用,反正没几个钱
这个我遇到过,就是你这现象
觉得以后可能越来越厉害,勤换机油,勤换FUEL FILTER, 用CLEANSER
看看能不能有所改观。我觉得那个CLEANSER有作用,车加速的时候
好像好了一些,也可能是我的幻觉,心理作用,接着用几次看看
射完了?
看到前面漂亮的车了
黄得不要不要的
throttle body 脏了踩 pedel 能感觉出来不丝滑,一顿一顿的
正解,需要清洗一下。
那些DEALER和MECHANIC好像对我的问题都没有兴趣
谢谢提醒,YOUTUBE上有教学,我研究一下,自己清洗一下throttle valves/body

现在的车全是电子throttle valves/body,不是传统的机械的了,你确信自己会清洗?电子的不会弄的话就直接洗坏了。

能不能讲讲你用的是哪种cleaner? 据说是会有些效果
