Why does my check engine light come on when I idle?

One of the least healthy things that your car does during the winter is idle for extended periods.

Either of these issues can lead to check engine lights.

• Engine won’t idle smoothly, idles too slowly, or stalls.
• Car accelerates, but won’t exceed a relatively low speed, or shift up.

What causes high idle speed in Hyundai Santa Fe?

Vacuum Leak: On any engine, a vacuum leak will cause a high engine idle as the oxygen sensor detects lean operation and the engine computer then tries to compensate, which can result in abnormal idle. Malfunctioning Throttle: A malfunctioning throttle system can cause both a high or low idle as well as an engine stall.

Why does my car idle all the time?

If the computerized engine control system is faulty, high idling can be one symptom. A vacuum leak in any of the hoses can be the culprit—inspect them all for leaks. A bad idle-speed control unit can cause the problem; it may need to be replaced.
