When excellerating my Jeep Cherokee feels like it is being sapped of power. When taking off from 1st to 2nd to 3rd, etc, it feels like it is struggling to reach optimal speed. I have recently replaced the spark plugs, battery, oil and muffler system with no noticable improvement. Any ideas?

Inspect and test all the following listed below:

Oxygen sensor
Catalytic converter
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
Cap and rotor

Note:If it doesn't apply disregard.
