    Guys,

    napansin ko kapag tinatanggal ko yung terminal ng battery for about 2 minutes tapos kabit ulit, ang sama na ng takbo ng kotse ko. akyat baba ang idle ko. kahit maikling andar lang tapos apak sa cluth babagsak ang idle ko to 300 hangang halos mamatay.
    pero after 1 hour or more of continous driving eh babalik na sa normal. kaya tuloy apak ako ng apak sa gas.

    94 Lancer Gli po.

    ano kaya problem nito?

    thanks gurus!

    maybe the ECU hasn't adjusted it's settings yet.

    disconnecting the battery is also resetting the ECU, so once you reconnect it and ran the car, the ECU is still relearning the optimum settings for your vehicle.

    so is this normal?
    pero ang tagal naman halos 1 hour?
    may backup battery ba ang ECU? para in case na tanggalin ang main batter kabisado nya pa ang settings?

    thanks

    Malamang nga nag-reset ang ECU. Walang back-up yun. So lahat ng soft memory niya mabubura.

    Pero kung bakit matagal siya bago nakapag-adapt, siguro ay dahil may mga sensors ka na hindi na functioning properly. (e.g. O2 sensor, cranshaft angle sensor, etc.). Dami kasing sensor na pinagkukunan ng readings ng ECU. Nakakabaliw.

    Sa susunod na balak mo bunutin ang battery, place a 9V battery connected to your cigarette lighter, para may backup at di mawala ang memory pati ng radio. :D

    it's normal for the computer to reset pero di naman dapat maging ganyan sya. have you done anything to your car? rewiring, etc? if so baka yun yung dahilan kung bakit ganyan.

    PK: I dont think may magagawa ka sa radio kasi yung +12 na live nya rekta sa battery yun not sa ACC. So anytime na ginalaw mo yung +12 na wire (yellow ata) magrereset yung radyo.

    Applicable naman alam ko sa radios, cigarette lighter and radio share the same fuse, depende siguro sa electrical diagram of each car make. Nakakapag sindi ako ng yosi sa ibang sasakyan with the use of the lighter even without car keys.

    Get hold of any dead celfone charger or new plug if not available, connect positive terminal to the 9V terminal and same with negative. Plug battery to 9V terminal prior to removing the car battery. Remove 9V battery before attempting to crank the engine to start.

    Wag mo lang bubuksan ang radio at magplay ng cassette tape. But the 9V batt can retain the memory until drains out.
