when stepping on the throttle alittle hard the engine acts like it has no power

Hello, I suspect there is a bad spot in your throttle position sensor (TPS) Try this: accelerate from a stop, but do so by slowly pressing on the throttle until the throttle is at full, then slowly back off of the throttle. Obviously you should try this in a safe location where you can safely move to 60-70MPH and back down. If there is a point in the gas pedal where the engine loses power, replace the TPS. If not, let me know.
