4runner check engine light at high RPM's

Hey guys,
My check engine light comes on if I run my truck at about 2700 RPM's for more than a few minutes. As the engine warms up, the RPM's at which it comes on gets lower and lower, how can I find out what the problem is? The check engine light turns off as soon as I drop it below 2500 for a few seconds. Help me out, Thanks.
