Misfire?

[Sabzz]

My grand prix keeps doing this weird thing. If I give the car more then 70% throttle, It will rev up to 5K rpm and not shift, The engine light will start to blink and it will lose power. Could this be a transmission problem or something? I've replaced the spark pluges and fuel filter. recently also had the whole lower intake gasket replaced along with the uppper intake.

wires or bad coil

Is there a way to test for that? Cause the car drives like normal, other then under heavy acceleration.
