Your engine is the heart of your vehicle. Over time, even the best engines start to lose their edge-hesitating at green lights, idling rough, or guzzling more fuel than usual. Sometimes, you notice sluggish acceleration on the highway; other times, it’s that persistent check engine light reminding you something’s off. Don’t wait for a breakdown.
