Can Bad Spark Plugs Cause a Lean Condition?
Yes, bad spark plugs can cause a lean condition. Here's how:
- Increased resistance: Faulty spark plugs increase electrical resistance, making it harder for the spark to ignite the air-fuel mixture.
- Reduced spark energy: Worn-out spark plugs produce a weaker spark, reducing the combustion efficiency.
- Incomplete combustion: When the spark is weak or delayed, fuel may not burn completely, leading to a lean mixture.
This lean condition can cause engine damage, misfiring, poor acceleration, and increased fuel consumption.
