My car isn't running as well as it used to. Is there anything I can do to get it running more smoothly?

One possible solution is to have your car serviced by a mechanic. This may involve checking the engine oil, air filter and spark plugs, as well as other parts of the car that could be causing problems. You should also check for any warning lights on the dashboard that indicate an issue with the car's performance. If none of these solutions help, you might consider getting an oil change or replacing the air filter.
