hey I'm having a code 9 on my 90GS, I replaced it with another unit and still gives me a code 9 after resetting. Going to try another one.

Where is the Iacv located and how does it look like? i may have to replace it since my idle is jacked up.

 

so you can get an idea

Located in the back of the intake manifold with 2 coolant hose connected.

 

two coolant hoses, two bolts, and a plug. has a black cap looking thing on it

 

thanks for the help, cleaned it and it idles much better!
