If you've noticed that your car feels sluggish, or just isn't its usual self, this could mean a few different things have gone wrong.
There could be a number of reasons your car feels slower and less responsive than usual. The best way to get to the bottom of this problem is to determine when this sluggish feeling happens, for example, during acceleration. After you've worked this out, it will be easier to determine what the most likely cause is.
If the sluggish feeling happens only when you are accelerating, this points towards worn or failing spark plugs. Your engine management light may also have come on to indicate this issue. In order to resolve this, you should have the spark plugs repaired or, if necessary, replaced by a mechanic to avoid the problem happening again.
If your car feels sluggish while driving, particularly towards the front of the vehicle, it is likely that your engine is misfiring. Misfiring can be caused by a multitude of issues. You should book in for an engine diagnostic with a great local mechanic to uncover and fix the problem at hand.
One of the other most common causes is a dirty fuel filter. These often get clogged up with dirt and debris, which in turns reduces the amount of fuel passing through them, stopping you from accelerating properly. If this is the case then it is simply a matter of replacing the filer.
