There are three sensors on my 98 lx throttle body and the one in the back says its the map sensor and the tan plastic one on the front left of the TB doesn't look like it does much and the one of the left of the TB doesn't have screws attaching it to the TB so I need to know where the AICV is so I can try to clean or replace it to fix my screwy idle.

 

Aloha and welcome to the forum. I will try to discribe the location of your aicv air idle control valve. on the throttle body is attached a throttle Position Sensor, ( may be attached with counter sunk allen screw head screws) attached to this is Idle air control valve (also called the electronic air control valve EACV) should be 2 bolts attached to the intake manifold. email me if you are still having trouble finding it.
