What causes loss of throttle response?
When the filter is dirty, it can cause a delay in acceleration and throttle response because when the fuel attempts to pass through a filter that is clogged or dirty, it takes far longer than it would through a clean filter. Staying on top of your fuel filter cleanliness is one way to prevent poor throttle response.
How do you reset the throttle position sensor on a Ford Focus?

This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.
