To fix a random cylinder misfire on a 2002 Daewoo Lanos, start by checking the ignition system, including spark plugs, ignition coils, and wires, as worn or faulty components can cause misfires. Next, inspect the fuel system for issues such as clogged fuel injectors or a failing fuel pump. Additionally, check for vacuum leaks and ensure the engine's timing is correct. If the problem persists, consider running a diagnostic scan to identify any specific error codes that may point to the underlying issue.
