All zth members, need some help to sought out my engine idling problem.
my engine idling after high rev is not stable where it drops to 300 or 400 rpm and sometimes do shutdown the engine. it is so difficult to drive in urban where u need to change gears always. my foreman did few troubleshoot such as changing ecu, airflow sensor, stepper motor, service throttle body and few more things but still the same. it happens with ac on or off.
engine spec:
-vr4 block
-evo head
-evo wiring...
