You're going to have to check everything over for vacuum leaks.

Check vacuum lines, your IACV, idle adjustment screw. All these play a vital role in your idle.

where is the plug for scanner located and what is iacv and where is that located? thanks

vacume hoses on what the idle control valve or on idle control motor ?

Check all the vacuum connections (there's not that many on a PGMFI Honda). You could take your intake off and seal your hand (or something) over the throttle body and see if it still runs, then you know you have a leak.

alright i fixed the problem it was the idle control valve on the bottom of the trottle body, but i got another one problem . My rpms are going up and down i replaced the throttle body gasket cause thats where the leak was still doing the same **** up and down etc. i replace the eacv still the same **** any ideas. thanks
