Several factors can lead to a P0307 code in your Ford Maverick. Here are some of the most common causes:

  1. Faulty Spark Plug: A worn or damaged spark plug can prevent proper ignition in cylinder 7.

  3. Fuel Injector Problems: A clogged or faulty fuel injector can restrict fuel flow to cylinder 7, causing a misfire.
  4. Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can disrupt the air-fuel mixture, leading to misfires.
  5. Engine Mechanical Issues: Problems such as low compression or valve issues can also cause misfires.
