This is a really dangerous problem that could get a person killed! My car will hesitate upon acceleration such as leaving from a side street to a main road or merging onto the highway. When you accelerate, the car will hesitate. You have to wait for a clear, big opening in traffic..unfortunately, the cars behind me don't know this and I get everyone all kinds of mad and honking their horns..GRRR!! Anyone else have this problem? How did you fix it?
