Is the idle adjustable on a 2002 Chrysler Sebring?

No, the idle speed on a 2002 Chrysler Sebring is generally not adjustable in the same way as older carbureted engines. The idle speed is controlled electronically by the Powertrain Control Module (PCM) based on various sensor inputs (like engine temperature, throttle position, etc.).

While you might find a screw that *looks* like an idle adjustment screw, messing with it will likely do nothing or cause problems. If your Sebring has an idle issue, the problem is likely elsewhere in the engine's control system and should be diagnosed by a mechanic. Things like a dirty throttle body, faulty sensors (IAC valve, TPS, etc.), or even a failing PCM could be the cause.
