不平则鸣

Thanks in advance to all the experts here,

My car 1999 Honda civic, totay it is suddenly showed up with the indicator of "engine check", and after I drived back home, I even get some strange smell inside the car like something burned. and I open the hood, there is nothing wrong there and no strange smell. after several hours, when I restart the car, the "check" indicator is still there.

Can any expert help me to telll what is the reason and how to solve it?

Thanks again.

Folks, DonCherry.....

Thank you again for your warm hearts. You are
really great guys...

According to your suggestions, I checked the
braking system and bearings in CT today. Both of
them are working well. That's for sure the noise
coming from the two poor rear tires.

>>>Tire noise plus shocks noise is called "Road noise",
   which usually come when you are on high speed. I am
   sure that tire noise does not come from tire at low
   speed. If u really want to find if the tire making
   noise, I suggest you find a friend with same size tire
   (185/70/R14?) and swap with yours. This could be easily
   done by you and your fiend.
   
   If tires are ok, then check shocks.

Since my car is so old, I'm reluctant to push more
money in it.(I've changed two brand new front
tires and it costed me over 200 bucks.) I just
wanna keep them rolling or exchange these two rear
tires. Is it a good idea?
>>>Yes, you do not need brand new tire, you should follow the
   thread before, where people found a place sells and
   installs used tires.

In the meantime, the mechanic recommended me to
change the "ball joint" of my right rear wheel.
But the price ****s----"200$", I prefer looking
around to get a better deal. The ball joint is a
little bit loose now, last time another guy found
the problem and used a big clamp to make it firm.
If I can't change it in time, it would be quite
dangerous?

>>>Are you sure you have "ball joint" in the rear?

Just a couple of days ago, I used the Fuel
Injector Cleaner. However, some friends told me to
use Fuel System Cleaner instead of it. Cause their
functions and results are so different.
Do you guys have any ideas?
>>> Yes, they are different, Feul injector cleaner is for
    injector. Fuel systemn 'TREATMENT' covers more, such
    as chamber, tank, feul line, fuel filter, intake valve,
    valve clearance, which could clean the carbon deposits
    build-up on those above parts.
   
    I suggest you to use both of them, but not at same time.

Open your hood, there is a small plastic stick on
the back of hood, from there, you can find all for belts.

If you dont want do it yourself, ask CAA to send
to Lujiang or Guoqing, $40 and 15min at most to
fix it for you.

peipei;
Apply it every 3k~5k. If you are going to have
long trip, say 500Km, use it for whole tank. Then
you will find th笤?r will be very happy for a
while.

fordescort;
Your car running a little bit lean on gas when it
warm. When it's cold, the mixture ratio of gas to
air is rich, so you have a nice start.

There are two possible parts need to be notice.
Coolant temperature sensor and oxygen sensor.
If you go to CT or dealer to do a emission check,
they will find problem for you.

But if the car is too old, just drive as it is.
Don't need money to fix this minor problem.

You should mention what symptom when you TURN the
key, I just image nothing happened when you turn
the key.

I guess there are reasons like, your battery run-off
due to some bad ground, or short.
Or your starter is dead.
Or your start relay dead if you cannot hear 'CLick'
when you turn the key.

Car wont start because of cold is usually minor
problem for garages, I recommend you go to the
cheap garage, where you may ask them to install a
used relay or start for you.

我的nissan sentra 88年的，一直较好，今天打火有点困难，之后怠速不稳，车子有些抖，起步困难，一丢油门就死火，刚换的机油和电瓶，这车有点上机油。请问folks和懂行的大侠，是啥原因，维修大概多少钱？谢谢

DonCherry

Your car has more problem then those fuel injection
car.

Try add "gas line de-ice" first, which can be found
in CT and check the resistence of spark calbe,
should be less than 100K ohm, better around 5k ohm

Then, you have lot thing to do. Such as,
Clean carburettor, new fuel filter, check fuel
pump, check spark, spark cable, distributor cap/rod. New air filter. check temperature sensor.
Add 1 or 2 bottle of fuel treatment.

Classic,

After you tell the sympton of sound when you turn the key, I
think the starter is ok but bentix inside it is crunching with
the fly wheel, which makes the noise like 'KaKa'. So your
battery is perfect, but bendix is worn out. Dont try start it
again, it will damage your fly wheel($$$) and kill you battery
in cold winter if battery run off.

Try to ask a friend to go to buy a starter and install yourself,
Nissan is much simple to fix than Honda. No one want fix bendix
for you, just buy a complete set of starter.
