This means that there is an excessive amount of fuel being delivered to the engine when it is idling, leading to a rich air-fuel mixture. A rich mixture occurs when there is too much fuel relative to the amount of air in the combustion process.
Common Causes of P2188 MINI
- Faulty fuel injector
- Malfunctioning oxygen sensor
- Clogged air filter
- Vacuum leak in the intake system
- Issues with the fuel pressure regulator
Symptoms of P2188 MINI
- Decreased fuel efficiency
- Rough idling or engine stalling
- Reduced power output
- Strong fuel odor from the exhaust
- Check engine light illuminated on the dashboard
