Stalling on idle can be due to a few reasons. Most common one is idling control valve caput. It's located under the throttle body. Sometimes, servicing it may help. Do this test. Park your car at idle, stay at Nuetral. Turn the steering wheel from most left to most right, see if the RPM raises. If it doesn't, time to replace your idling control valve.

Another one is MAF sensor. When the car dies, check engine light will come on. MAF sensor also have a symthom where at full throttling, the boost will fluctuate up and down vigorously.

I had my MAF sensor replaced. A new one costed me RM1.4K 2 years ago.

[stutzedward]

Sometimes it helps. When I say service, it includes cleaning of throttle body too. Can do at Ah Wah la. Hehehehe.

i already do the test steering wheel turn, rpm no raise. normal

 

[stutzedward]

if RPM doesn't raise, then yr idling valve is the culprit.

if RPM doesn't raise, then yr idling valve is the culprit.

so is time to service the valve

sometimes servicing may help... other times, you need to replace em.
