Hi guys,

Engine stock, just changed fuel pump and battery.

If the problem happens after you changed your fuel pump, highly possible due to that. Send it back to the mechanic to check.

I got a question to ask you ... why do you change the fuel pump and the battery at first place?

Issit because the car stall prior?

If this problem happened after you change the fuel pump and battery then please go back to your mechanic and request a fast check up !

If prior this your car is having this problem too, it can be a mis-diagnosed by your mechanic.
#1--The culprit maybe a loosen aged fused that prevent your battery to be charged
#2--A faulty wiring system that keep dropping your voltage while driving
#3-- for example like a faulty alternator, short circuit electronics
#4-- in an unlikely event, but happened, is a faulty exhaust system where like the catalytic converter or something inner had block up the airflow exit the exhaust and make it choke after it get hot.

But the first thing you need to do is to send it back to your mechanic who fix the fuel pump.. it can be as simple as a loosen connection ...

maybe the Idle control valve not working properly.. my car do stall quite few times. it is because of blow off valve. need to reflash to minimize that problem.. now the idle control valve start to show symtoms.. damm..

bro 4gbanger, have you remap your ECU? Ask the tuner to check your idle map. If it has been changed before, restore the factory idle map will just solve the problem.

im not sure my car has been reflash or not from previous owner but the ECU now is placed at the foot area. i did not reflash it yet but i know the idle control valve start to create problem as the aircond or steering turn during idling makes the idle drop..

i thought that was normal??? :hmmmm:

 

[4gbanger]

which part was normal bro faruck? did u mean the idle drop due to steering turn during stop? the idle control valve suppost to give some vacuum support so the idle does not drop below idling rev.

 

[stutzedward]

The ecu is located at the passenger side and only the obd2 port below the steering column. On idling, if steering is turned, rpm sud either stay or go up. If engine dies, yes the idling valve is gone.

 

[4gbanger]

well mine if turn steering engine not dies yet.. maybe soon..

 

[stutzedward]

You can actually ask Ah Wah to take it out for you and 'service' it. It will help a bit.

 

[4gbanger]

will do.. soon
