• Reduced Fuel Economy: A noticeable drop in miles per gallon can suggest problems with the fuel system, ignition system, or engine itself.
• Rough Idle: If your Hyundai’s engine vibrates excessively or runs unevenly at idle, it could indicate issues with spark plugs, fuel injectors, or vacuum leaks.
• Loss of Power: A decrease in acceleration or difficulty maintaining speed can be a sign of serious engine problems, such as low compression or a failing fuel pump.
• Unusual Noises: Knocking, ticking, or whining sounds coming from the engine compartment should be investigated promptly.

• Faulty Spark Plugs: Worn or damaged spark plugs can cause misfires, leading to reduced performance and fuel economy.
• Clogged Fuel Injectors: Dirty or clogged fuel injectors can disrupt the fuel delivery process, resulting in rough idling and loss of power.
• Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can affect the engine’s air-fuel mixture, causing rough idling and performance issues.
• Low Compression: Low compression in one or more cylinders can significantly reduce engine power and efficiency. This can be caused by worn piston rings, damaged valves, or a blown head gasket.
• Sensor Malfunctions: Faulty sensors, such as the oxygen sensor or mass airflow sensor, can provide incorrect information to the engine control unit (ECU), leading to various performance problems.
• Timing Belt Issues: A worn or broken timing belt can cause significant engine damage, potentially requiring a complete engine rebuild.
