• Faulty Crankshaft or Camshaft Position Sensors
  The crankshaft and camshaft position sensors are crucial for proper engine timing. If these sensors malfunction, the engine may misfire due to incorrect timing. Check the sensors and replace them if they are faulty.
  
• Faulty Mass Air Flow (MAF) Sensor
  The MAF sensor measures the amount of air entering the engine and sends this information to the ECU. If the sensor fails or becomes dirty, it can cause the engine to run poorly and misfire. Cleaning or replacing the MAF sensor can resolve the issue.
  

• Worn Piston Rings
  If the piston rings are worn or damaged, they may fail to create a proper seal within the cylinder, resulting in low compression and misfires. This is a more serious issue that may require an engine rebuild or replacement of the piston rings.
  
• Damaged Valves
  If the engine's intake or exhaust valves are damaged, they may not seal properly, leading to compression loss and misfiring. A compression test can help diagnose this issue, and valve repair or replacement may be required.
