at idle cold or warm the idle speed can be from 250- 2000 back and forth. And when i start driving the car cold it sort of chuggs along for a minute or two till it warms up then its fine and doesn't do it any more. These seem like two totally unrealated problems. Any suggestions where to start trouble shooting.

air filter
throttle body
air flow sensor
spark plugs


do honda's have an Idle Air Control Valve?
