Where is the IAC on a 99??? The black square thing to the passenger side of the TB is the TPS right? What is the black thing on the driver's side of tht TB? looks like a cylinder shape.
Well, the white one going into the manifold looks like a coolant sensor. I see a hole around the 7 oclock position in front of the throttle plate and you can see the bulge on the outside on the passenger side of the TB, is this routed from the PCV to bring back in to get burned???
On the 98 the IAC is on the top passenger side. on mine, I dont quite see it. Anyone? so quiet here [img]redface.gif[/img]

the black thing on the driver side that has a flexible metal hose going into the TB is your EGR unit. see how it goes from the manifold to it with a wire going into it to the TB. thats it. IAC, not sure, i'll look it up in my manual tomorrow
Well, I cleaned out the frt side of the plates and the housing forward of the plates. Can't really reach that far back unless I remove it. Car is smoother and is more willing to accelerate now. It sounds smoother too [img]smile.gif[/img]

yea, I know that's the EGR, but there is a 3rd fuel line that goes into a black cylinder thing which then goes into the ~2 oclock position of the TB if you standing in frt of the car. I think that might be the Vapor storage canister line,.,.,.gotta be

after looking at my throttle position with autotap i am pretty sure the drive-by-wire throttlebody does not have a IAC motor. the computer just moves the throttle plate. at idle i see the plate open to about 4.5-5%.
if you look closely i believe you can spot a blockoff plug where the IAC should be.
