    For a few weeks now my car is slightly rough ideling mostly when warm :( it has every so offten triggered the engine management light. I had it run on a diagnostics today and it came up with the following codes

    P0172 selfadaptation of mixture formation, the mixture is too rich in the part load range

    P0304 misfiring cylinder 4
    P0302 misfiring cylinder 2
    P0301 misfiring cylinder 1
    P0303 misfiring cylinder 3

    The car runs fine when on the move just seems it be when in idle in traffic the revs are sounding slightly in stable?

    I have a feeling it may be the MAF and I would like to clean it. Dose anyone have any diagrams on how to locate and get to this part. Any help at all would be well welcomed

    Thank you :)
