Hello forummers,
i need some help and opinions here regarding my gsr engine.
i got a stock 4g93t gsr engine in my putra, stock engine, stock boost, stock piping, stock everything la. car have been running fine for 2 years now until recently.
whenever i full throttle, the engine seems to have sudden jerk/cut off like theres a boost/fuel cut or something (feel like i hit a wall). the engine didnt die and check engine light came off for a while then dissapear. have to accelerate low or mid, but not full.
i dun think its a boost cut coz im running on stock boost. well although i dun have boost meter (dunno wat boost im running at), i havent done anything to increase the boost whatsoever.
what do guys think the prob is? my mech said maybe its a faulty actuator valve. ur guys opinions is appreciated.
cheers.
