my mechanic said that my AAc valve is reading low numbers. what does it do and wear is it located? thanks for the help- he says this is why my car is sputtering and rough idle hopefully!!!

 

I think you mean IAC - the idle air control valve.....cost like 3.50 and very easy to install....dont let him rip you off! It takes like literally 1 minute to install once you find it....

 

do you know where its located?

 

I forget....near the front exhaust manifold, underneath somewhere its hard to see...I am sure someone will chime in with a pic....Ive seen one in another thread but alas no search....

 

thanx ill go look for it, do you know symptoms of a this part acting up?

 

It does NOT cost $3.50 (I'm sure it's more than that...) Look at the upper intake manifold pic here: http://forums.maxima.org/showthread.php?t=335886 you see the pink, purple, and brown connectors? That's the IACV. Disconnect the connectors (just like in that pic) and then take out the 3 screws and clean out it out with some throttle body cleaner.

There is some info in the How To thread at the top also. Here some info/pics I have saved from before for my personal record: http://www.jatan.net/IACV.doc (right click and save target as...)

 

mine was 3.50...its a little plastic tube! Got it from autozone....my mechanic installed it for free while I was getting other stuff done.

 

You're probably talking about the PCV valve...

 

**** man I think your right...sorry!
