Checking engine spark is a crucial step in diagnosing ignition system problems. It involves testing the spark plugs to ensure they are generating a strong enough spark to ignite the air-fuel mixture in the engine’s cylinders. A weak or absent spark can lead to engine misfires, rough idling, and decreased performance.
The importance of checking engine spark cannot be overstated. A properly functioning ignition system is essential for efficient engine operation and optimal fuel economy. Regular spark plug inspections and replacements can help prevent costly repairs and extend the life of your engine.
