What causes an irregular idle speed on an Infiniti I30?
You’ll notice an irregular idle speed if there something wrong at the Infiniti I30 valve location, just as with the 2000 Nissan Maxima idle air control valve location. Idle speed won’t be maintained at a constant rate. It can be too high, too low, or surge in repeated climbs and falls.
When does the idle air control valve change?
When the engine is running but the vehicle is not moving, this means the engine is idling. During this time, the number of revolutions per minute (RPM) inside the engine will change. The idle air control valve is responsible for managing the engine idle speed.
When to do idle air volume learning in Nissan Murano?
Each time electric throttle control actuator or ECM is replaced. Idle speed or ignition timing is out of specification. Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied.
What causes the idle speed to randomly fluctuate?
It will cause the idle speed to randomly fluctuate to different speeds rather than stay at one constant speed. The idle speed may be too high at one moment and then too low at other moments.
What to do when your car is at high idle?
While observing the valve with a flashlight, turn the key to the “ON” position, (DO NOT START ENGINE.) the valve should move slightly. Step 3 – Engine vacuum is a sealed system and must hold a specific amount to maintain proper idle conditions, inspect the engine vacuum hoses and intake gaskets.
What’s the difference between high idle and low idle?
Step by step automotive repair guide on how to troubleshoot and fix an engine that is idling high (fast) or low (slow). (Note: The engine idle speed is controlled by the computer and is NOT adjustable.)
How can I check the idle air control?
To perform a rough check of the idle air control, remove the valve while reconnecting the wiring harness. While observing the valve with a flashlight, turn the key to the “ON” position, (DO NOT START ENGINE.) the valve should move slightly.
Can a bad idle control valve cause stalling?
This is controlled by the engine’s computer. Sometimes parts go bad, which results in your car idling strangely or stalling. Check to see if your idle control valve is functioning properly before attempting to replace it. Look for a high engine idle. A common symptom of a faulty idle control valve can be a high idle.
How can you tell if an idle air control valve is working?
Disconnect the IAC connector for a couple seconds while your engine is idling. If your engine idle didn’t change, you can suspect it to be the IAC. If it is working properly, unplugging it would cause your idle to freak out. Also check the wires going to the IAC connector.
What should I do if my idle control motor is disconnected?
The engine should still start and run without any issue despite the idle control motor being disconnected. Be sure to tuck the wiring you disconnected up in the engine bay so it doesn’t get caught in any moving parts. Look for a difference in idle speed.

What causes a car to stutter at 500 rpm?
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.
What to do about idle stutter on Nissan Leaf?
1. Clean the throttle bodies with throttle body cleaner. Used the method of disconnecting the negative battery terminal and removing them but leaving the electrical connection intact. They were, as expected, filthy. 2. Vacuumed out the air intake boxes.
