For an engine to run, it needs three things: Air, Fuel, and Spark. If any one of these is off balance, your car will run rough, lose power, or fail to start entirely. Fuel and Ignition diagnostics focus on the components that create combustion: spark plugs, coils, fuel injectors, and fuel pumps. If your car feels "jerky" under acceleration or takes a long time to crank over in the morning, we use live data analysis to see exactly which cylinder is misfiring or if your fuel pressure is dropping under load.
A misfire feels like the engine momentarily "trips" over itself.
