hey guys need a hand:

Lexus gs300 with a 2jz ge wont rev past 3000 rpm, it is hitting some sort of rev limiter. It isn't throwing any codes at all, have checked all the o2 sensors, have reset the ECU, checked battery, pulled all the vac lines and let the engine breath but nothing.....

Gets to 3krpm and just cuts, only thing i can think is the ignition module might be cactus? crank angle sensor maybe?
