Idle Relearn

The idle being low could be due to a couple things but more then likely we need to force the ECM to relearn the idle.

Here are a couple guides that will help with this issue just to get us started:

We should check the throttle bore and make sure it is not dirty. If it is then we need to clean it. Here is a guide that will help with doing this:

If none of this works let's try this process to try and trick the ECM into relearning the idle.

• Remove EFI and ECTS fuse in under hood fuse box for 3 minutes
• Reinstall both fuses
• Hold the throttle plate close completely with your finger
• Have someone turn ignition switch ON
• Release throttle as soon ignition is ON
• Reinstall throttle body boot, start engine and let run at idle for 5 minutes before road test

Idle speed should be between 550 and 650 RPM's

Let us know what you find. Thanks
