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)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

So what was the solution? I've got a very similar problem with my 2002 Alero 3.4L. Finding this problem is rampant with the Alero cars once they get around 100K, but can't find a single posted solution.

My solution was my Catylac converter had to be repalced, which resolved my issue returning the power and gas milage my Alero should have. Cost was around $200, which is pretty reasonable considering all the things that could have gone wrong.

Before taking it to a mechanic for their expert opinion (where the CAT was diagnosed), I had replaced the fuel filter, air filter, cleaned mass air flow sensor, and checked my spark plugs. The car had not thrown a serivce engine code until the day before I took it to the mechanic and it was misfire code, which apparently is common with a CAT problem.
