On 1991 acura integra were is idle air control valve located?
The 1991 Acura Integra idle air control valve can be found on the firewall. The valve will be on the drivers side of the firewall.
== == == == == == == == I have a 1991 and the Haynes manual only shows the removal/installation of the EGR valve on the Legend models. What I find odd though is that there is an EGR part for the 90 - 93 Integra and it's not cheap.

The EGR valve is located on the intake manifold right at the rear passenger side corner of the cylinder head. It has both vacuum and electrical connections to it. Also identifiable as having a long vacuum hose running from the EGR valve directly to the EGR control unit which is a large black box mounted to the firewall behind the ABS pump.
