Question about Nissan Maxima
Hey want to know what has happened to my nissan maxima 2004, at idle when you start hot or cold, it idles very low almost likes its struggling to breathe. done some research on the matter and reckon might be iac, do you know where this is located and how to clean it and clean the throttle body? thanks matt
It will be located on the throttle body. You should be able to find a suitable throttle body or carb cleaner at your local auto store.

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.

i had a similar problem a few months ago with my se-r. i went to the dealership and had them reprogram the ecm and it fixed it(its on the recall list for your car.) once i did that everything ran great.

After about 100K + miles the idle air control valve (IAC) begins to collect carbon deposits that interfere with the movement of the spring-loaded valve. You will not be able to clean this without removal and dissembly of the IAC body. Use an emory cloth or fine sandpaper to remove the build up around the valve. This should free it up to rotate without binding. This is a temporary fix, of course, and will either require cleaning again or replacement of the valve. Getting to the IAC requires removal of most of the intake upto, but not including, the intake manifold. Total time is approximately 3-4 hours, but worth it. Good luck, and I hope this helps.

No..you can't adjust the idle...
Possible cause---Electric throttle control actuator, intake air leak or PVC system...check these 3 things...
