How do you adjust the idle on a 2002 Nissan Xterra?
Start engine and warm it up to normal operating temperature. Rev engine (2,000-3,000 rpm) two o three times under no-load (A/C OFF, headlights OFF, radio OFF), then run the engine at idle speed. Adjust the idle speed by turning the idle speed adjusting screw.
When to do idle air volume adjustment Nissan Xterra?
Each time electric throttle control actuator or ECM is replaced. Idle speed or ignition timing is out of specification. Before performing Idle Air Volume Adjustment, make sure that all of the following conditions are satisfied. Learning will be cancelled if any of the following conditions are missed for even a moment.
How long does it take for an engine to idle from a cold start?
It controls the idle no matter what state the engine is in, hot or cold. Second, when the engine is cold, the computer is in open loop and goes to closed loop once the engine has met all of its presets. Can take up to two minutes on most modern fuel injected vehicles.
Is the starting idle RPM always lower in colder weather?
However, in the warm temperatures (when the temp sensor reads 40°F (4°C) or above), it’s always starting up with a 1.6K RPM idle, no exceptions, unless the engine is already warm. When the engine is warm, the RPM is generally around 600 to 700 RPM when idle. Is it normal for the starting idle RPM to be much lower in the winter?
What does low idle mean on a Nissan?
1. Stuttering/low idle/near stall/stall when stopped in gear 2. Upon warm restart, engine idle would drop below 500 rpm and almost stall, 3. When cold, at light throttle input, a stumble/stutter around 1,700 rpm that almost felt like a transmission slip. 4. When cold and in 5th gear but low speed of around 40 mph, the car actually bucked.

How to adjust idle speed on Nissan Frontier?
Transmission: Warmed-up (Drive vehicle for 10 minutes.) Start engine and warm it up to normal operating temperature. Rev engine (2,000-3,000 rpm) two o three times under no-load (A/C OFF, headlights OFF, radio OFF), then run the engine at idle speed. Adjust the idle speed by turning the idle speed adjusting screw.
How can I tell if my idle control motor is working?
Look for a difference in idle speed. Allow the engine to run for a minute so it settles to a consistent idle, then take note of any difference in the idle RPMs versus the idle you observed earlier. If the idle has not changed at all, it’s likely because your idle control motor has not been functioning.
Why does my car stall at low rpm?
The will likely force your computer to stall the engine and only allow it to run at low RPMs, which means the car will only move at slow speeds. This is a safety feature enforced by the computer so that your engine doesn’t get too damaged.
