common problem for wiras since the using of siemens ecu and this caplang TB.
start ur engine. disconnect the hose from airbox to TB. pull the 'cable to control throttle opening' then spray generous amount of carb/tb cleaner inside.the engine might show u sign of wanna die-off.no worry.keep pressing the throttle.
i m sure alot of wiras user keep a can of this cleaner handy. u need to do it every 2-3 months
