After warms up when pushing the accelerator the engine rpm oscillate and there is not power. Also, when applying a lot of power from a stop the engine jerks. It has a 3800 engine.

- the wires and plugs are new.
- Injectors were cleaned. There were very dirty. The fuel pump check valve hasn't been cleaned.

Once the car downshift is has plenty of power. Also, it has a lot of power always when it is cold.
Also, suddenly it appears some times to gain power.

The rpm oscillation is similar when you press the accellerator and let it go when the torque converter is not locked. It looks to me the power is fluctating causing this.

Forget the head gasket thing, or the catalytic converter. The new "cats" are a fine mesh, it is doubtful that one could clog up.
The distributor cap, if you have one, could be defective. Look for vacuum leaks, that could cause the lack of power as well. As for the engine RPM oscillating, is this the Tachometer, or is the engine speed going up and down on it's own? If this is the "tach" then there is a problem with the pick up from where this device connects to the engine. It's probably slipping after the engine warms up. Another possible engine jerk source is that the transmission is low on fluid. This could also cause a lack of power, or the engine jerking.

it could be this
bad cat convert what needs to be replaced
or bad head gasket

Sounds like an ignition miss. That is the ignition system has a fault. Would be more pronounced once the engine is warmed up.
