What to do about Honda engine hunting idle?
The most important part of the procedure is to back it off 1/4 turn after you bottom it out. You won’t find one of these on EVERY Honda engine BTW, mostly on engines older than 1997. The later model engines just use the IAC to control fast idle on a cold start up.

Why does my Honda Civic idle too high?
When cold you just get an idle that is too high like up around the 1200-1500rpm range or higher. The second video shows a vacuum leak that I found on a Civic using a ‘safer’ method for checking for vacuum leaks. Both work but the important thing is that you check for vacuum leaks if you have a Honda idle problem.
What’s the problem with my Honda Civic engine?
Honda Civic Engine Mount Problems Many Honda Civic drivers report strong vibrations or a rattle when they drive their vehicles or switch gears. This is often due to faulty engine mounts that are no longer providing suspension and support. Engine mounts are typically expected to last the lifetime of the vehicle.
Why does my Honda Civic stay on the road so long?
Honda Civics have a tendency to stay on the road for a decade or more. Whether it’s due to years of use or a manufacturing issue, Honda Civic owners have been dealing with transmission problems since the beginning of the century. Transmission failure is a serious and costly problem to face.
What does hunting idle mean on a Honda?
The computer also fights them as it tries to maintain an idle using the IAC but it can’t keep up so you get a ‘hunting’ idle condition meaning that the idle fluctuates from high to low and it never levels out. This condition is often worse after the engine warms up.
How can you tell if your Honda Civic has a transmission problem?
Transmission failure is a serious and costly problem to face. You can detect the early signs of transmission failure if you hear whining or clunking noises while driving. If your car is stalling, unable to move or leaking transmission fluid, that could be another sign of early transmission failure.
What does it mean when idle control does not increase?
If the engine idle does not increase, it means there is an issue at the idle control motor of its circuit preventing the signal from changing the idle. You can purchase a bidirectional scan tool at your local auto parts store. Make sure the wiring harness is firmly connected to the idle control motor before conducting this test.
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 an idle motor to exaggerate the hunting?
Vacuum leaks are a big cause of exaggerating the hunting. The idle motor doesn’t have enough power to overcome a lot of “False Air” or air leaking into the induction system after the air sensor plate. A big and common source of leakage is old injector seals.

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.
