The square plug coming off the sensor on the throttle body on the right hand side. There will be a flat one and a square one coming from the same sensor.

First off, search throttle body and IAC cleaning and do that.
With the engine cold sometime, snug up the bolts holding the intake manifold on.
If you're gonna need to mess with the TPS after that, the FLAT plug should be unplugged to see if the idle changes. That's the one for engine controls. The square one is for the auto trans.
