I have a 1997 camry with over 100,000 miles on it it seems to hesitate a little after I accelerate from a stop. It doesn't make noises and the idle seems fine. I have had a throttle body cleaning but it didn't seem it seem to affect any thing but the
accelerator not sticking . Is this normal?

Hesitating/stumbling

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
