The idle speed is not adjustable on this car. It has fuel injection, so the computer is responsible for controling the idle speed.
You can adjust it on carburated engines, but not on injected ones. (At least that's the idea. There is a throtle position bolt somewhere around the air intake throttle, but it is highly unrecommended to touch it.) So, look for other causes of bad idling.

Not so fast ! you can change the air adjustment and it will speed up or slow down the rpm. I saw the Nissan Man do it with a screw driver.YES!!!
The shop manual has a specific procedure to adjust the idle speed.
How do yu adjust idle in a nissan sentra
There should be an idle screw right by or under your throttle
May be computer controlled and not adjustable
Its probably has a vaccume hose leak.
On a 1992 Acura Vigor idle is adjusted through a idle control valve. Tightening the valve well raise the lower the idle and loosening it will raise it.
Your idle reglator needs to be adjusted so it idles at a higher rpm
Fuel injectors
AH yes. I actually like mine! It's the Idle air control valve on the back of the throttle body. There is an idle adjust screw facing the front of the car. If not adjusted properly, or if you need a high idle due to vacuum loss from a nice extreme cam, it will whistle. Also, if it's a Cali car, it might be the vacuum valve for introducing air to the exhaust system, although I have never seen this myself.
You don't. The ecm adjusts it.
Not adjustable, idle is computer controlled with an IAC stepper motor.
The fast idle-speed on a 1994 Nissan D21 pickup is adjusted by turning the screw on the side of the throttle body. It increases the speed of the engine when the vehicle is idle before completely warming up.
If your Nissan is '97 or newer, there is a computer mounted below the passenger seat that controls idle speed. Remove the 4 bolts holding the passenger seat, take it out, and use a flat screwdriver to adjust idle speed. make sure the engine is off and adjust only a little at a time until the desired rpm is attained. Be warned, it might affect emmissions test.
