    fault codes P0100 and P0219

    My engine's running very rich, lumpy and has no power at all. Tech 2 found the two codes P0100 and P0219. I tried another air flow meter but it's still the same, checked all the vacuum pipes and everything looks normal. Anyone got any ideas as to what this could be or how to remedy it.Also the two lambar sensors vault readings were 475 mvolts and the other was 800 mvolts, should the readings be this far apart between the two?

    PO100 - im certain is the AFM, A quick google search confirmed my thoughts.

    PO219 - appears to be a "engine overspeed condition" ??
    It appears to be related to Air flow to the engine air intake / throttle.

    If that is the case then it would figure....fautly air flow reading to intake due to faultly AFM!

    Can anyone else add to this???
