Hi Everyone,

What is the problem of engine stalling, when I waiting for the traffic lights in (gear D)?
It also has no problem if the restart engine again.
If the driving time has passed for a while, this will not happen.
Especially when the engine does not warm it seems easy to stall.
Sometimes the engine seems to be stalled when backing up (gear R), but no stalled.
I replaced the ignition coil, spark plug and cleaned the throttle body for this, but still have not solved it yet.
Anyone can help me solve this problem? Thank you.
(My car is X308 MY2002 3.2L)

 

Do you have any codes?....is the Check Engine or Restricted Performance coming on?
MAF would be the next thing to clean, be sure to use a MAF only cleaner. A test you can do, ...and you'll need to clear the code after, is to disconnect the MAF, the ECU will go into default upon startup and allow the car to run. Performance will be hampered, but you'll be able to drive the car on a limited basis.
Be sure to check vacuum lines also for leakage.

 

Also check the voltage on the battery while the engine is idling and with the AC and headlights on. If less than 13.5 V, it could be your alternator not providing sufficient power (voltage) which can cause all sorts of problems.

 

Dear Highhorse,

There was no engine code and Restricted Performance code come out.
I have already cleaned the MAF before is used by MAF cleaner.
I will check another vacuum hose for leakage.
Anyway, thank you for your advice.

 

Dear M. Stojanovic,

Thank you for your advice.
Actually, I replaced the new battery in a while, after a few months the battery became weak,
and the engine cannot start, then I charged the battery, the engine can be restarted,
even if the engine was not warming up, I did not stall, I felt there was power.
So I think is time to replace the new alternator soon.

 

If you have an Android phone, buy a ELM327, in your location they cost next to nothing.
Then install a program like Torque or Torque Pro on your mobile, they are in the App store, also just peanuts money (mine came as a copy with my ELM327 from China ).
It needs a bit of setting up, but it will provide you with a wealth of information, which then might give you a clue of what is really going on.
We can help you there if it looks abracadabra in the beginning ...

 

Have a look at fuel trims at idle to see if there's a vacuum leak.

I suppose a bad engine mount might cause such a stall.

 

 

You use an OBD device. You can do it in a suit if you like, no parts swapping involved

 

from the issues I had,

battery
MAF
ignition coils
spark plugs
ABS module

start your searching.

 

Dear Vincent,

Thank you for your advice.
I will check it again.
