Hey does anybody know where is the idle air control valve is located, and how to go about cleaning it..?? i have a 03 350z

 

You can clean the throttle body and maf sensor. Then do the idle relearn procedure.

 

tha problem is i cleaned tha throttle body and i got a idle air control valve code.. so i did tha relearn procedure it fixed it for a sec then i got a code again.. and its idleing at like 1000rpm....

 

What code do you have? I'm almost sure there is no IAC valve. If you look in you'll find no additional valves or limiters in the throttle body. The job of a IAC is performed by the throttle body, ECM, and MAF working together.

From what you said in the previous post I would visit your local auto part retailer, pick up the specific MAF cleaner and clean the MAF. After that, perform ALL the relearn pedal dance proceedures and see where you are.

 

There is no IACV. Are you sure you plugged the throttle body back in?

If so, try all the relearn procedures again since timing is crucial and sometimes they won't work.

 

I discontected tha battery complety and unplugged tha throttlebody and let it sit for 13hours and it got fixed after i pluged everythin back in!
