While cleaning the throttle body this weekend, I decided to remove the idle air control valve (IACV) and clean that too... I tried to follow the instructions posted in the FAQ, but I'm not sure I understood them correctly... here is what I did.

I removed all the connectors and 3 bolts (12mm) that hold the entire IAC assembly onto the throttle body.

Ok now how what? All I see there is a round cap covering some type of hole? (on the side that was toward the throttle body. I clean all this off - so the round cap is all shiny (sorta gold/bronze colored - like a new bolt)... and I tried to clean up everything under the cap.

On the side where the connectors are, there were two phillips screws that let another piece of the IAC assembly come apart - (with an o-ring sealing that seam)... so I clean out that piece and the plastic dome-like thing (techinical huh?) ...so I cleaned that up... now on this smaller piece, there were yet another two philips screws that presumably hold the actual IAC valve in place.. is this what I should have opened and cleaned? I didn't do that because the Haynes manual said the part is electrical and shouldn't be messed around with...

I don't see how cleaning what I did is going to help anything - which part of all that moves to control the idle and what exactly should I have opened up and cleaned?

Its driving me nuts and the Haynes manual is useless on this subject...what "should" I have done..?

Any help?

You did it right. Spray some down hte tube and scrub it out with a brush or rag.

 

By tube, do you mean the tube that leads into the throttle body? I did spray a bunch of TB cleaner into there and tried to clean it up as much as I could.

 

the copper tube that a hose connects. The hose is connected to the midpipe.

Filter - MAF - MidPipe - TB - Intake Manifold - IACV connected to intake manifold.

 

Even though I have no idea what you are talking about (at engine components at that level), I'll take a look under the hood when I get home and see if I can figure it out... I'll post back with my success/failure in an hour or two..

thanks,

That is order of hte intake on our engine to let you know what is what

 

I got it - so you are suggesting that I clean out the hose/tube that connects between the intake manifold and the IACV... just to be sure I am finally on the same page - this is the only tube I had to disconnect from the IACV before pulling it from the car... right?.. fortunately I can clean that tube easily..

 

Well you don't need to clean the tube itslef. But the copper tube hte rubber hose connects to on hte IACV

 

got it... thanks for all the help...
