Generally. replacing an engine is pricier than repairing or replacing a transmission. The engine is the vital organ of a car and its intricate design requires additional labor and parts. resulting in higher costs. However. one should not underestimate transmission issues as a complete replacement can also be very costly. particularly for vehicles with advanced automatic or dual clutch systems. The price will vary depending on the vehicle's make and model as well as the use of original manufacturer parts versus aftermarket options. Luxury or high-performance cars have especially expensive components due to their technical complexities. Proper maintenance of both systems is crucial to avoid expensive repairs. Investing in preventive maintenance is a smart decision when considering the expense of replacing an engine or transmission.

Q why does an engine backfire

An engine backfires primarily due to unburnt fuel igniting outside the combustion chamber. This can happen both in the intake manifold or the exhaust system. Key reasons include timing issues, where spark plugs ignite the fuel at the wrong time; fuel mixture problems, either running too rich or lean; and issues with the car's exhaust or intake valves not opening or closing properly. Poor engine timing disrupts the precise sequence of intake, compression, power, and exhaust strokes. If a vehicle's engine runs too rich, excess fuel remains unburned, while a lean mixture might cause the engine to overheat, also leading to backfire. Faulty or clogged components, like spark plugs, fuel injectors, or air filters, can exacerbate these issues. Regular maintenance and ensuring that all engine components are in good working order can help prevent backfiring.
