    lately my car has been getting the check engine light.
    I open the bonnet and it's still there ....
    it's a VY S2 calais LS1

    so seriously I'm thinking it could be a faulty oxygen sensor
    it does it when the motors hot or cold.
    mainly when I'm going slow like in a car park.

    Most of the time before it happens i notice the instant fuel usage can climb to over 50L/100km
    and it starts running rough the light comes on.

    If the light is on and I get it cruising on the open road it seems to dissappear. like not go to the small icon on the side of the dash but completely removed from the display. I assume it must fix itself when it's basically running at a constant speed.

    I have taken it to holden dealer but they said they can only do a scan if the light is flashing.

    worst thing is I haven't been able to get it to come on when holden are open.

    I did replace the oxygen sensors 2 yrs(10k) ago.
    (One of them is a prick to change)

    I still have my old ones if the scan shows it is that can i put an old one in or should I get 2 more new ones?

    I have heard swapping sides can fix it?
    or any other ideas?

    Ok so tech2 pulled up code p0134 bank 1 sensor 1
    so it's an O2 sensor
    any idea what side? holden dealers said they think it's left hand.
    done a quick Google but conflicting answers.
    All say p0135 is bank 1 sensor 1 drivers side
    I'm guessing it could be American drivers side so that would be our passenger side?

    AFAIK bank 1 is the bank that has the number one cylinder so that would be left side/passenger side. IMO o2 sensors should both/all be changed at the same time. I wouldn't bother keeping any of the old ones.

    I just changed 02 sensors on my vy ss , they cost me $ 90 for both with free postage on ebay . they are bosch , made in the USA . i was not getting the engine light on at all , but car was running rough and using lot of fuel 19 lts / 100 kms . now its down to 15 lts / 100 kms. thats just short drives say 5 - 10 kms. so worth changeing them. cheers.....
