    Decarbonizing is known also as an italian tune up. I usually do mine at nlex and sctex, preferably very early in the morning (3am or earlier). Just go there and floor the gas pedal. Make sure your brakes and tyres are up to the job before attempting this PMS.

    Then it is not the gasoline, it's the engine. Have the timing checked first. Then have it decarbonized. Carbon deposits lead to a condition known as "dieseling" wherein hot carbon parricles in the cylinder act as an ignition source, causing premature ignition of the fuel-air mixture. The resulting symptom is engine knock. In extreme cases dieseling can cause an engine to continue running even when the ignition has been turned off (not so with engines with electric fuel pumps though).

    try mo din sir reset ng ECU,
    disconnect the negative terminal of the battery for atleast 5 mins,
    connect it again and drive around the block for a few times to have the ECU relearn
    its settings.

    If you do plan to do this, make sure to have the car go thru the idle learn procedure before driving it out.
