Lost of Torque

I have a 98 Trans Am, and for some reason there seems to be less torque when i give my car a decent amount of gas then around 3000 rpms it starts to pick up like it should..no engine light..i have know idea why it is doing this

has anyone had any similar problems? i know it could be a number of things and this question is quite vague with the info i'm giving you but anything would help...just throwing this out there but could old spark plugs and wires do this??? If you need me to tell you anything else just ask..
thank you

Has it always been this way, or is it a change from the way it previously acted?
If you notice a good increase in power at 3K (and always at 3K) it may be the engine 'coming up on the cam'. It is normally the grind of the cam that causes it, and it is generally about half way through the RPM range for a street car. Of course computers can vary that quite a bit on newer engines, depending on how it is setup at the factory. My Colorado has it, although it is not as obvious as a more powerful engine. If I push the accelerator about half way down, and hold it there as the engine/truck is accelerating, all of a sudden about 3K, I notice a surge in power output that holds as long as it is above 3K.

it is called power ban.

The computer does learn how you drive. Sorta.

Getting warmer out...could be some of it. Warmer = slower.
