Another common symptom is engine misfires, which can lead to a rough running engine and decreased performance. Symptoms of misfiring include:
- Unusual vibrations felt while idling or driving.
- Loss of power during acceleration.
- Check engine light activation.
- Increased fuel consumption.
Overheating
Overheating can be a serious issue that may lead to significant engine damage. Signs of overheating include:
- Temperature gauge reading higher than normal.
- Steam or smoke coming from the engine bay.
- Coolant leaks under the vehicle.
- Unusual noises from the engine, such as knocking or tapping.
Knocking Noise
A knocking noise from the engine can indicate a serious problem. This sound is often described as a tapping or knocking, especially during acceleration. Symptoms of this issue include:
