lets say im sitting in my driveway and had just started my car. If i were to turn the AC on, it would take my idle from about 900 to dead. If im driving down the road, and turn it on...once again i lose about 500 rpms...
Isnt something in the computer supposed to correct this automatically for me?

 

Sounds like a bad idle air control motor, it should compensate the idle for the additional engine load.

 

thats what i figured. Just didnt know the exact name.

 

Yeah, well you test it by ohming the coils and see if they are any good.
