Why does your Seat leon 1.8 turbo engine stutter in neutral?

A stutter in a Seat Leon 1.8 turbo engine while in neutral could be caused by several issues, such as a vacuum leak, faulty spark plugs, or a malfunctioning fuel injector. Additionally, problems with the ignition system or a dirty throttle body can disrupt the engine's airflow and fuel mixture, leading to irregular idle. It’s advisable to check for diagnostic trouble codes (DTCs) and inspect these components for proper functioning. Regular maintenance can often help prevent such issues.
