    ECU reset, fuel filter/pump/relay. I'm talking not only for Nissan Cefiro specific here.

    Try spraying the MAF sensor with CRC contact cleaner. Be very careful with this MAF sensor as this is very delicate. Just spray the wire part, but do not touch it. My Nissan Exalta'02 had the same problem, and I was able to cure this by just cleaning this sensor. You can buy the CRC contact cleaner in Tru-Value or Robinson Handyman.

    hindi ako familiar sa behavior ng mga makinang may ecu, kung traditional na engine yan... i'd say check your fuel filter, fuel lines and fuel pump.

    Nung meron pa akong space wagon 4g93, nangyari sa akin unbalance yung engine, parang sa apat na cylinder, merong isang di gimagana. Found out after several troubleshooting and googling, one injector di na gumana. So nag diy ako, remove the injector. Replaced it with surplus and na clean ko pa other injector. Baka kailangan lang incjector cleaning assuming spark plugs and its cable are ok.
