Misfire Detected with Low Fuel
Misfires are detected while the fuel level is low. The ECM disables further misfire reporting under this condition because intermittent fuel starvation can cause false positives in catalyst-damaging logic.
Affected components
- Fuel tank
- Fuel level sensor
- Fuel pump
Common causes
- High likelihood: Fuel level very low
- Medium likelihood: Weak fuel pump or pickup
- Low likelihood: Faulty fuel level sensor
Possible symptoms
- Check engine light on or flashing
- Rough idle and uneven running
- Power loss, hesitation under acceleration
- Increased fuel consumption
- Possible smell of unburned fuel from exhaust
