I was wondering if the IAC has any relation with the torque convertor OR cruise control meaning does it control either of them in any way? Reason I ask is because mine was faulty so I unplugged it and manually set the idle but my cruise doesnt work and the TC doesnt lock up. Dont know if they were working but Im told the cruise was. I dont wanna plug it back in beacause it took a while to manually set it and it idles fast when its plugged in so I thought I would ask first. That and there 62 bucks which is kinda high to me. It idles fine just kinda runs like a carb when its cold. Thanks!

 

Manually setting idle on a computer controlled car is not good. Replace it, and put the TB back to stock setting.

 

Its been running like that about 5 months now .Just took its first long trip and noticed it wasnt locking up.
