Engine
Spark plugs & ignition coils
Healthy spark plugs and coils ensure a firm start, smooth idle and controlled consumption — when they fail, the engine shakes and loses power.
What we do
Spark plugs create the spark and coils supply the high voltage for it. Over time they wear and cause misfires. We diagnose with a scanner, identify the affected cylinder and check plugs, coils, leads and connections before recommending replacement.
At Mr. Service we use plugs with the correct specification for your engine and verify the proper torque and gap, details that make a difference in performance.
Warning signs
Engine shake, a lit check-engine light (misfire), power loss, hard starting, higher consumption and jerking on acceleration are typical signs of plugs or coils near the end of their life.
Driving with a misfire overloads the catalytic converter and can lead to a far more expensive repair. Replacing on time is a simple, economical maintenance.
