I have a 2006 ford focus with 21000 miles I think its a four cylender. I was going to the store last night when the was trying to accelerate the I would hear the engine reve but the car would not accelerate and then it would sound like it moved out of gear and then jerk forward. Now this morining my husband said there is a knocking sound from under the hood.
