How do you do this? Where is it located?

I know where mine is, but I need to know how to effectively do this as well.

I as well would like to do this. My mechanic told me it was difficult to do on my car because the MAF sensor is so far away from the throttle body that the car would die in a few seconds because with the tubing taken off, the ECU would think there a lack of air and thus reduce fuel to a point where the car would stall. Is this true? Do you have to 'sneak' the cleaner in via a straw attachment to the aerosol can and have a friend rev the car high while you inject the cleaner between the seal of the ribbed tube and the throttle body opening? That's my theory. Anyone care to confirm? (I'm speaking about my VE engine, VG is prob a little different.)

trying to keep it at the top till a palitable answer is given.

What you do is remove the intake piping that connects to the throttle body. Then use a rag dipped in simple green and clean the front and rear sides of the throttle plate along with the entire inside of the throttle chamber. Actually try to clean back as far as you can reach. AFter your done you should note a smoother idle and better fuel economy. If your car suffers from a hunting idle at times just remove the idle up soleniod or AAC and clean that out. Over time these parts get dirt and grime inside.

You can also clean out the idle air control valve by disconecting the air line that runs to it and squirt alot of cleaner in the hose, then reattach and start the engine. Repeat this several times and this will clean out the IACV, AAV, also the fast idle control solenoid. The Air hose that I'm talking about is the one located after the MAFS on the right hand side, slide the clip back and then spray inside the hose and then reattach.

When I finished this my idle rose a whole 200 rpm. This is because of all the carbon depoits that had been flushed out.

It's not on a Maxima, but you can go to twinturbo.net, then the Tech section for the throttle body cleaning (I did the writeup). The layout is different but the process is the same.

You do not have to do it with the engine running. The won't run if the intake tubing is pulled off anyway, so don't try

Don't use Simple Green - the throttle bodies have a special coating on them and abrasive products can eat through the coating. ONLY use intake throttle body cleaner - definately NOT carb choke cleaner.

I cleaned out my TB about 2-3 months ago and it ran great...for about a week. Now it's back to it's old self. I thought that you weren't supposed to spray any liquid down into the manifold past the TB. I used a clean shop rag and sprayed the TB cleaner on it and wiped it out. Is there a better way?

When I talked to my mechanic about it, he said that you spray the cleaner into the throttle body, where it would remove the coke and other deposits and then send it all to the (high revving) engine where the liquid would just ignite and burn away. It makes sense to me -- I'm sure the cleaner is highly flammable, and can burn off when combined with the spark and some fuel.

It's not a problem to have the throttle body cleaner work it's way through the system. It'll actually help clean out carbon deposits on the underside of your valves. I've cleaned about 30 throttle bodies in the last year, all with the same method.
