Your car’s computer monitors hundreds of issues and systems, but there could be problems that it doesn’t pick up. So you have to listen to your car. To smell its odors, feel it’s vibrations, and get in touch with its soul. Alright, maybe that’s a bit much, but if your car is making a new noise—rattling, squeaking, going “Ga-Gronk, Ga-Gronk” when you turn left—have a mechanic take a look. If something starts to smell weird, it might be the yogurt you spilled that time, but it might be a problem with your catalytic converter. Some problems can present as changes in how the car drives. A lack of acceleration, using more fuel than usual, vibrations, harsh-shifts, or lurching, could all indicate something is wrong. Don’t ignore these signs and omens.
