How do you do an idle Relearn on a Ford?
Follow these steps to complete an Idle Relearn: With vehicle at a complete stop, set the parking brake. Put gear shifter in “P” (Park), turn off all accessories. Run the engine until it reaches normal operating temperature.
What’s the best way to idle a car?
Run the engine until it reaches normal operating temperature. Allow engine to idle for at least one minute. Turn the air conditioning on and allow the engine to idle for at least one minute. Release the parking brake.
Why do I have an erratic idle after loading a tune?
In the event you are experiencing an erratic idle after loading a tune or after performing any action that clears KAM (Keep Alive Memory), an Idle Relearn can help you get back on track. The KAM or “Keep Alive Memory” is the memory that is stored in the powertrain control module (PCM).
How do you adjust the idle speed on a Honda Accord?
If you need to adjust the idle speed as well, wait to put the air filter back on until you’re finished. Find the idle adjustment screw. There is an idle speed screw that adjust the opening of the throttle plate, and an idle mixture screw that limits the flow of fuel at idle. You want to adjust this second screw.

What causes a rough idle or a ses?
A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration. To correct any accidental changes in throttle body calibration, use these procedures to recalibrate. Note: These procedures are a little tricky to do. You must get the timing just right Use a stop watch to help the precision of your timing.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
How to clean the throttle of a Pontiac G6?
3. Clean the throttle body bore and the throttle valve plate using a clean shop towel with ETech Chemicals ET110 Throttle Body Cleaner. 4. Install the air intake duct. Refer to Air Cleaner Inlet Duct Replacement. 5. Perform the Throttle Learn Procedure.
How to do throttle body cleaning and idle relearn?
1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds.
What should the idle time be on a Chevy Malibu?
1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds. 5. Start and idle the engine in PARK for 3 minutes. 6. After the 3 minute run time the engine should be idling normal.
When to release the throttle to idle position?
Quickly release throttle to idle position once CKP sensor variation learn procedure fuel cut off is obtained and engine starts to decelerate. Once CKP sensor variation values are learned, the PCM will return engine control to the operator and engine will respond to throttle position.
Why does my Ford Mustang idle at 800 rpm?
The car had underdrives on the crank and waterpump before I bought it and the volt gauge does not go up until about 1000 rpm. Even with this the car would idle before at 800 rpm. When I added the parts in the sig, the engine would not idle at all. The car died every time it came to a stop.
What does it mean when your engine idle does not increase?
Use the command in the scan tool to increase the engine’s idle. 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.
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.
