poor idle

    Hi, my vts is hunting on idle and sometimes the eml comes on but not at the same time. would a sticky icv cause the eml to come on?

    Hi,

    No the engine warning light is not set by the ICV. However a misfire will cause the engine warning light to come on momemtarily. You'll need to track the problem down to either fuel mixture or electrical.

    However, the ICV could be causing the erratic idling.
