Need help here, 4AGE 16v (AUTO)

[babylck]

i'm driving a AE92 with 4AGE 16v w/o TVIS (AUTO).. the problem is everytime when i rev to higher than 2500 rpm the 'check engine light' will turn on.. i need to slow down a bit for awhile only the light will go off.. anybody here encounter this kind of problem before? how can i solve it? its really annoying/scary to see that 'check engine light' stay on when you driving at 100+ km/h when you have to rev above 2500rpm.. thanks in advance..
