I have changed spark plugs, spark plug wires, fuel filter, fuel pressure sensor, coil packs, full tune up. So when I go to push the gas peddle in it loose power somewhere. There is no check engine light on r nothin could u help tell me the next step. I also had the car scan at three different places.

Your description of "It loses power" isn't very detailed at all.

Is it misfiring?
Is it a hesitation?
Is it a smooth loss of power at higher RPM?
Is there ay surging or backfiring?
Is it worse when the engine is cold or when it is hot?
How did this begin?
