I'm looking at the TB and I dont know where the IAC is. I took off the MAF sensor, and in front of the Throttle Plate on the 7 O'Clock position I see a hole, is this hole routed from the PCV valve??

To the passenger side, that looks like the TPS. To the driver's side I see a black cylinder shaped thing going in and is connected to the fuel line, what is this??

 

On the 98 and down (with cable operated throttle), the IAC is a separate solenoid. I believe on the 99 and up (with electric throttle) the IAC is managed by the electric throttle motor opening and closing the throttle blade just a bit.

The 7:00 hole is PCV feed.

I have a 98, so I'm not sure on the black plastic thing, but I'm going to guess that it's the evap solenoid, and the line going to it is the vapor line from the tank. If it has a test port (yellow cap I think) in the line somewhere, then that's definitely it.

 

oh, that makes more sense now.
