Spark plugs ignite the air-fuel mixture in gasoline engines. Aarrow Transmissions & Automotive helps Glen Allen and Midlothian drivers plan spark plug replacement using the engine specification and service interval. If rough running or a misfire is already present, we investigate the cause before assuming plugs are the answer.
Plug type, access and replacement procedures vary widely by engine. Using the correct part and installation method matters, and related boots or ignition components may need inspection. A misfire can also be caused by a coil, injector, wiring or mechanical fault.
Tell us about warning lights and previous tune-up work. Diesel engines do not use spark plugs for combustion; confirm the appropriate service for your engine.
Intervals vary by engine and plug specification. Follow the manufacturer schedule rather than assuming one mileage applies to every vehicle.
Not automatically. Coil condition, test results and the engine design guide that decision. Ask the shop to explain any related parts recommended.
