    my problem is when the aircon is on, the engine idle is rough. sometimes the car stalls during neutral. when the auxilliary fan automatically turns on, ok naman nasa 1000 rpm yung tach reading. pero pag nag auto off, bumababa yung idling ng .400 rpm minsan lower kaya nagstall minsan pag naka neutral. pero pag nag auto on yung auxilliary fan, balik 1000 rpm ulit yung idling. pag naka-on lang naman yung aircon nagiging rough yung idling. ano kaya yung problema peeps? pls help. ride ko pala '97 exsior. ty.

    Same problem with mine, pero intermittent siya.

    Baka wiring problem sa a/c, may grounded somewhere, or yung idle-speed controller (or its nearest counterpart sa mga Toyota) mo may diperensya na.

    ako din pag ng kick in na yung fan bumababa yung idling from 800 to 500-600 rpm kaya nanginginig yung kotse.

    try to check yung karga ng battery...go to a reliable battery shop
    or an auto electric guy to check the output voltage of the battery
    kainlangan yata is 14volts pa rin ang reading nito kahit
    bukas lahat ng lights and accessories mo..even yung aux fan...
    and malalaman mo rin dito kung sira ang alternator mo..

    ang nangyayri naman sa akin..pag sipa nung dalawang aux
    fan parang lumalabo ng konti headlight ko..pero bumabalik din
    naman...and hindi naman rough ang idle....

    Could be a failing or dirty idle air control motor/valve.

    hijack at buhayin ko lang muna itong thread...

    problem ko rin ito, rough idling pag naka on yung aircon. while driving ok naman. pag off yung aircon ok na rin. malinis naman yung IACV. tapos pansin ko yung idling di nagbago nung on yung aircon.

    meron rin bang idle up screw or whatever you call it sa PGM-FI (fuel injected) na engine?

    ok naman cguro yung battery nito dahil wala pang 6 mos., yung spark plugs naman around 5k km pa lang. na-reset na rin pala yung ECU dati.

    vehicle is a 95 honda accord

    problema ng yung 4afe ko just this morning:

    pag nag-off yung aircon merun whining sound sa engine bay. after mga 5 seconds mawawala yung noise, then bababa naman sa 500 yung rpm. when i step on the pedal balik sya sa 800 rpm. vacuum problem kaya to? idle-up switch?

    btw, brand new battery ko.
