I've been reading all the previous posts on idle and stalling and it appears I need to clean or replace my Iacv. Can somebody post a picture of one for me please(preferably in car). Can I just replace the thing--would that be a bolt it in and go proposition. Also on my way to this question I changed-rotor-cap- fuel filt-and cleaned out my throttle body---pressure tested my fuel line---31psi not running 40psi at idle--is that high, the chilton book said 33 at idle.I'm not noticing any black smoke issues. I also after reading the threads here took the advice of the Nissan tech and spayed throttle body cleaner into my 1" hose by the radiator-no appreciable improvement. I also pulled each injector 1 at a time while running to see if there was one that made the least difference--nothing I could notice. My car has 268k on it--178k of which are my miles--I had the engine rebuilt about 4000 miles ago--all the injectors but one are original--------It's been a great car for me I just need to get past this hurdle----thanks in advance!

It's a 91 240sx base model with a KA24DE-sorry for leaving that out.

it's wrapped up by the runners of the intake manifold. Pretty easy to get a screw driver to the only phillips head screw if you look down from the runners but a real chore to pull off and replace.

The IACV-AAC valve is a small box located on the back side of the intake manifold.
