Engine problems can arise from various issues, affecting a vehicle's performance and reliability. Common symptoms include strange noises, reduced power, or warning lights on the dashboard. These problems may stem from low oil levels, faulty spark plugs, or issues with the fuel system. Regular maintenance is essential to prevent engine problems. This includes checking and changing the engine oil, replacing air filters, and ensuring the cooling system is functioning properly. Addressing minor issues early can help avoid more significant repairs and extend the life of the engine.
