车停着等红绿灯的时候，会忽然轻微哆嗦一下

[BCQ1]

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

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

[BCQ1]

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

空调关了也不行，AI说是throttle valves/body脏了

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

[BCQ1]

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？

[fukwumao]

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

[guagua1220]

正解，需要清洗一下。

[BCQ1]

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
