I'm driving a Toyota AE92 with 4AGE 16V (Non TVIS) Auto.. Can any sifu here teach me how to check my ecu error code in details? Cause the problem is everytime when i rev my car above 2500RPM, the 'check engine' light will turn on and only will turn off if i slow down my car (rev below 2500RPM).. Really need your helps.. Thanks!
