Acceleration stumbles & bogs down when gas pedal is applied. This scenario occurs all the time when after a normal acceleration is performed and a need arises to accelerate occurs. If you depress accelerator immediately upon taking off this does not occur but, it causes you to over correct stumbling by speeding quickly. If you need to accelerate, the engine will not respond to a normal depression of gas pedal. You need to depress it quickly to cause the engine to go into passing gear etc. My "auto wise" son has suggested that the gas pedal drive by wire sensors could be failing or be bad etc.
