求助：发动机抖得比较厉害

[TOMMY-STAR]

如题，开的时候不抖，N档P档都不抖，只有在挂在D档踩着刹车停着的时候抖得厉害，比如等红灯的时候~



06年mazda3，7万公里，平时保养的都不错，也没别的毛病。



请问各位该检查哪？

 

[hunksalim]

我原来的mazad也有过同样的问题。后来清理了发动机有一个什么valve，就ok了

 

[TXK]

可能该tune up了。一般是换发动机的火花塞。换机油。

 

[alacarte]

用seafoam清洗。

 

[Teddy]

Could it be an 'engine jump' situation, due to a loose mount on frame?

 

[路顺]

用seafoam清洗。

I do not think so in this case

换了火花塞和连接的4条电缆，就再没这毛病了，

建议尽快修理，不然问题会越来越大，

And you think , 70000 km and have to change those "连接的4条电缆"?

My old car bought brand new in 1992, changed those wires in 2005, with over 400,000 km. It seems that MAZDA cars (or just Mazda 3) have QUALITY problem! Don't buy Mazda 3.

“with over 400,000KM", V5~

It retired last year March, over 18 years of service, 560,000 km +. Never have transmission problem. Start and go in cold winter. Changed starter once, battery twice, alternator twice. Old cars are usually better built then new cars. The make and model is used by a lot of driving instructors in Toronto. (I met my driving instructor back in 1997, and he told me his car has over 700,000 km, and he still used it to teach....).

Agree, maybe the car is a LEMON car. (I read some reports that Japanese cars have an average of 12 % lemon, what percentage do you think is American?)

7万公里，never change spark plug, hard to see.

我咋看着是传动系统的问题哪？
放在空挡，不抖；只是传动齿轮分开了；发动机还是在怠速。

Since your car is 06年mazda3 which means your warranty expires, if not, go back to dealer, that may be a major component problem.
I think there are many (honest and excellent) mechanics who are members of CFC and they are willing to give you a thorough check.
Don't count on luck. The mechanics are professional.

我家的车也是这个毛病， 请问修火花塞大概多少钱啊，以前去修，他们只换了4条电缆， 没换火花塞。。。。。。收了几千刀，还是没有修好。

4条电缆??几千刀 ?
a good quality generic costs less than 200, can last for at least five years.
Original from dealer may be a little bit more expensive and should expect that to last at least ten years. A mechanic (not dealer) will charge you one hour of labour (at most). Hence, should be less than 300 CAD.
还是没有修好? I think the mechanic is incompetent or not honest (or both).
In Ottawa, I go to Ming or Dragon.
** If the job is 几千刀, then you have to ask mechanic to show you the wire that the mechanic has removed, and open the hood to show you the new one.

I recommend you try to fill in your tank (full) with Petro 91.
