Installed the 703's today, and disconnected and touched the cable ends together.....Started her up and the check engine light came on. Disconnected and touched the cables together for 30 seconds, reconnected, started and the check engine light still comes on. The idle is up around 1150 from 750.
I checked all connections, and are secure. Checked for any chaffed wires...no joy. Wiggled the harness around while idling, and no difference.
Any leads/ideas....thanks

 

whats the code?

 

Sorry,

The IAC was unplugged, but still in the housing & not making a connection. Case closed
