I recently changed the battery on my 2002 ford focus and now it runs different. Well, it still feels smooth and sounds fine but the rpm will go all the way to 3,000 before it changes to second and third gear. It also makes a hard change of gears or however you say it. Whenever I change gears it feels hard on the car. What do you think it is? It used to change gears very smoothly before I changed the battery.
Why does my car run different after changing the battery?
