    Default 2.2 direct running rich

    My 2.2 direct is giving bad mpg after having a service ( oil ,filter, plugs, tb cleaned) but is still only getting 26mpg combined. I had my friend put it on opcom and no faults but it was saying that it is running rich and the air intake is showing 32degrees when its 10degrees outside. No management lights on and driving fine but Could it be the maf? Or lambda?

    The maf is easy to clean. Front lambda is easy to change. The rear one is tricky. I had a faulty rear lambda so mine was running rich. Around late 20's mpg. Changed the rear one and sorted. Bit it did show an O2 fault on opcom.

    Maybe it needs a better diagnostic done. Tech 2 or the dealers or something.
