Iab/iac?

[Mac]

I pulled 411 and 412 and when I searched, many people said check the IAB connector. What is this and where is it located? Same for IAC.

IAB (idle air bypass)=IAC (idle air control)

It sits in the intake across from where the filter line hits the intake. It is a gray canister about 5 inches long with a 2-wire clip coming out the back (towards the firewall) of it.

It keeps the car idling when not on the accelerator.
