February 10th, 2010 07:57 PM #2pinagalaw mo ba aircon mo recently?
punta ka sa aircon shop or gas station na my magaling na mekaniko...
tapos ipa-set mo yung idling twice: pag may aircon at wala. yung mekaniko na hahanap ng tamang idle speed nyan pag naka aircon o hindi.

February 12th, 2010 04:21 PM #3Hello Efren,
please ask you mechanic to check you relays for your ECM/PCM and conection between the MULTIPLEX CONTROL UNIT3...it shows that even you compresor is up, your ECM/PCM still on idle-up mode which is normally off when the aircon compressor is off too. The solution is that to check, if your tempcontrol unit, on your console has good connectivity to your ECM/PCM which send the signal to your engine. All this can only be check if your aircon mechanic know exactly whats wrong. VTEC3 idling is control by the computer... ask him to check connectivity to the dash console. or call me I'll tell him what color wire to look. ...
Happy motoring.
happy Honda mechanic
