When I try to accelerate, the engine RPM's will increase dramatically with very little speed increase. Knock sensor, control module, plugs-wires, catalytic convertor and fuel pump replaced within 10,000 mi. Any suggestion would be appreciated, thanks...

Check and test all the following listed below:

Oxygen sensor
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
Cap and rotor

Note:If it doesn't apply,disregard.
