Recently we had a car owner bring his car to us. He said that the car had no power and when he was pulling away into second gear there just was no power. He thought it mght be the alternator or even something worse.
The fact is that your batter needs to power the car sprak plugs and if the batter power is not suficient it might only power some or only one spark plug. In that case the car will feel as if it has no power!
Get your battery checked regulary to ovoid being stranded at the side of the road.
