-High idle before your car warms up, above 1500-1800rpm
-Lumpy idle (especially on Neutral Gear)
-Roaming idle
-Hunting idle
-Fluctuating idle
Try to check and clean your IACV (Idle Air Control Valve) and FITV (Fast Idle Thermo Valve)
.For those of you who maybe didn't know what IACV and FITV is maybe these information might help
The IACV is located on the side of the Intake Manifold, while the FITV is located under the Throttle Body (TB) mounted to the TB it self
Quoting from http://www.ef-honda.com/ben/Badidle.php
The idle on our Hondas is a tricky thing. It is controlled by two main sensors: the FITV and the IACV. The FITV is a mechanical valve that is controlled by coolant temperature (there is no ECU plug to it). When the coolant is cold the valve is open and letting air into the IM through a hole in the TB before the throttle plate. This essentially creates a small vacuum leak which in turn lets the motor idle higher than normal (supposed to be around 1500-2k for warming up). As the coolant warms up the valve closes and no longer lets air in through the hole in the throttle body. All the while the IACV, which is ECU controlled, is letting small amounts of air into the IM through another hole in the TB. Any amount of extra air the ECU is not expecting will confuse it and you will get either a high idle or a roaming/hunting/fluctuating idle
