Has anyone tried this? (Supposedly this is in the manual. Let me know if it works.) On another forum, someone did this to resolve idling issues and vibrations at idle:
Perform the Idle Learn Procedure
To ensure a steady engine idle, perform the idle-learn procedure after installing the No. 29 (10A) fuse. During PDI inspection.
NOTE: The PCM does idle speed adjustment; there is no adjustment screw. Idle-learn must be done whenever you reset, update, or replace the PCM, or replace or clean the throttle body. It does not need to be done after you erase DTCs with the HDS software on ETecH, or after the battery has been disconnected.
1. Make sure all electrical items (A/C, audio unit, defogger, lights, etc.) are off.
2. Start the engine with the shift lever in P, parking brake on, and hold the engine speed at 3,000 rpm until the radiator fan comes on.
3. Let the engine idle for 10 minutes with the throttle fully closed.
You can turn the car off after 10 minutes. That's it! This is for ALL Honda/Acura's.
