Restricted fuel delivery and malfunctioning spark plugs are the most common reasons for cars to hesitate during acceleration. The first step to identifying the cause of this is to find out if the car is fuel-injected or if it has a carburetor.
In a large pan mix the water and vinegar. Gently add the berries and gently remove them to a colander to drain. Repeat this washing and draining. After they have drained, remove the berries and place them on a cookie sheet lined with paper towels. I place this in front of a fan or under a ceiling fan until all the berries are very dry.
When you're ready, wash each berry differently. Blueberries can take about any method, apart from a long soaking. Strawberries, with their delicate, absorbent skin, require a little more care: Quickly swish unwashed berries in a bowl of water, move them to a strainer, then move them to paper towels, placed in single layers and let them dry.
