What causes problems with acceleration?
What Causes Acceleration Problems? Hiccups in air and fuel delivery and sensor issues are the main causes of poor acceleration. However, mechanical issues can also be the cause of low power.
Why is my car sluggish on acceleration?

Did Toyota fix the unintended acceleration?
On November 25, 2009, Toyota amended its floor mat recall involving the same 3.8 million vehicles sold in North America. Toyota will reconfigure the accelerator pedal, replace the all-weather floor mats with thinner mats, and install a brake override system to prevent unwanted acceleration.

Why is my car hesitating when I press the gas?
Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating. To resolve the issue, please request a diagnostic for poor or rough acceleration.
