Is it electric throttle? If so, it won't have one.
That is, is there a cable to inside the passenger compartment, or not? If so, the IAC will be in the same general vicinity as the throttle plate. If not, well, it's all handled by the ECU and there is no IAC.
Thank you! I came to the conclusion yesterday that it didn't exist even though my parts supply store adamently suggested it did. However, I would've never known to associate it with the throttle type. Much appreciated.
