I have a 5AT Z here, however, I drove with maunal mode today, and full throttle it for many times......but the engine stall on me after the fifth try of full throttle. does anyone know whats wrong with my car?? the check engine light did not on, it just stall.

 

Is your car completely stock? What modifications have made? a little more information is needed before anyone can help you.

 

Could be any number of causes: a vacuum hose that's loose, a faulty sensor (oxygen
sensor?), etc. Sometimes, the trobleshooting section in the Owner's Manual will help solve simple stuff; give it a shot, kid. Good luck. Oh, I DO post here whatever it was
that caused the miss/stalling of your engine, please!
