View Full Version : IAC valve - Speed Governed?

08-01-2010, 12:35 PM
My '94 Maristar 225 VRS was idling low and dying. I removed the IAC valve, cleaned it, and now the engine is idling around 1200 rpms. When I look for replacement IAC valves they are offered as either - "speed governed" or "except speed governed".

Does anyone know which one it should be?

Thanks - Jon
