Infiniti QX4

Having idle issues with your Infiniti QX4 ECU?

This page is specifically about Infiniti QX4 ECUs, usually 2000 - 03 range, that have been damaged by the Idle Air Control Valve shorting out, often burning the circuit board.

Usually the Infiniti QX4 ECU that
has been damaged by the IAC will still be in repairable condition.
It depends on the extent of the damage to the ECU, some are worse than others, but most units can be restored.

You must replace failed IAC with brand new Hitachi IAC or the overhauled ECU you receive back from us would be damaged by it after re-installation.
