Will a dead battery still spark?
If your battery is bad, it may cause sporadic sparks in the engine’s combustion chamber which lead to poor ignition of the fuel-air mixture. The result is more fuel accumulating in the engine combustion chamber which is then passed along partly combusted into the exhaust.
