    Default I Need to follow a fuel tanker

    Still Averaging 24mpg even after long runs

    The car is a 2.2 direct (not the most ecenomical engine) but i have read post on here that most people are averaging 33 - 36 mpg.

    The emmisions light is on and Had the scanner on the car and is showing
    p0136 02 sensor circuit malfunction (bank 1 sensor 2)

    Firstly am i right in thinking the 2nd sensor would not effect fueling etc as its main role is to check the condition of the cat.

    What other things would you reccomend that may be causing such low mpg, there is notecable flast spots from 1200 - 2500 rpm

    I will be replacing filter and plugs...is there anything else that i could be looking at, would cleaning the egr make any difference


    Thanks

    I'm pretty sure there is a precat on the 2.2 (don't know that much about them though) The second sensor would be after the pre-cat but before the main cat. If its giving false readings the car may well be overfueling thus the poor fuel economy

    Thanks for the reply john, i dont think there is a pre cat, had the car on the ramp at work and noticed lambda 1 at the manifold, cat at the down pipe then sensor 2 then a small silencer.

    maybe the non direct has the pre cat

    Cheers

    Ok after doing a bit of looking you are right, however the O2 sensors are there to control fueling so that is where I would start especially as that is one of your faults

    Next things to do is replace air filter and plugs, clean egr and try this airbox mod thing that everyone keeps mentioning worth a go

    What about the coolant tempreture sensor. It might be telling the ECU it is still cold, so it might be over fueling.??
