A 2002 S10 may surge at idle speed due to several potential issues, including a vacuum leak, which can disrupt the air-fuel mixture, or a faulty idle air control (IAC) valve that fails to regulate the engine's idle speed properly. Dirty fuel injectors or a clogged air filter can also contribute to inconsistent idle. Additionally, issues with the ignition system, such as worn spark plugs or ignition coils, might cause irregular engine performance. It's advisable to perform a thorough diagnostic check to pinpoint the exact cause.
