My chevy lumina (when taking off and before it switches gears and cannot figure it our

I have replaced the plugs, wires, gas filter.
i have checked the coil packs all working properly.
I have had the fuel pressure checked it is 43psi

I cannot figure out why it will do this if you take off really slow and dont give it too much gas starting from a stop it will do ok. It only seems to do it at a higher rpm.
please try to lead me in the right direction
thanks

Could be compression, timing, or a fuel system needing cleaning.

Nope. Generic answer. If it's timing, it's a sensor or computer issue.
Check the crankshaft position sensor at the end of the crank on the right side of the engine. Make sure it is properly installed and gapped.
