Adjust that little set screw under your throttle dog on the TB.

It's tiny but they come loose and adjust themselves lower as you drive.....mine finally fell out and that's what was causing my "stalling when clutch is depressed" / "low idle when coming to a stop.....then comes back up" problems. I taped a spacer in there till I get a new one from NISSAN and my idle is rock solid again.......at 900 because the spacer is slightly too big.

Edit: If you are looking at this that means you searched......Thank you.

The NISSAN dealership doesn't even have a diagram showing the screw location, I tried that already, but I'll explain furthur.

Look at your throttle body.

Ok. Now look at the circular part on the passenger side of it that the throttle cable hooks too. This is your throttle dog.

Now lift the throttle dog and notice the metal bar put there to stop it at it's lowest position. (idle)

In the middle of this metal bar is a small black screw. The bottom of this screw has a 8mm nut and a TINY allen key hole. This is how you adjust it's hight, and in turn, your idle.

Mine fell out so there was just a hole there and I have now adjusted my throttle cable to get the dog to the right hight at idle. This is a temp fix till I go to the junk yard and get another screw.

Sorry if that was kinda confusing. Look at it.....you'll see what I mean.
