Hello. I usually start by checking the computer for codes. I also use the scan tool to see what the sensor are reading. Most of the time this is caused by an airflow sensor that is not reading right or a failing throttle body. It can also occur if the vehicle needs a tune up or if the timing belt is worn out and stretched. All of these need to be checked. If you need to have this checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your acceleration issue firsthand.
