    Well just had this code flag up.

    Symptoms :rough idle immediately after start, doesn't really want to to go for a split second after releasing key, 500 or so rpm.

    Has done this twice now, two month or so apart, this is the first time a fault code has been registered.

    Idles fine once it picks itself up.

    MAF was replaced 'bout year ago after completely different symptoms of overfueling...

    X4 plugs replaced 3 weeks ago iridium ngk [real ones] old plugs X3 colour fine grey brown. X1 light cream......plugs were however WELL overdue having been replaced some 30k before I bought it some 50k ago.

    coincidental / red herring items.....?

    Last time this occurred was after fuelling from a particular ASDA. Guess where I'd just fuelled from again.

    Seems to happen after a heat soak.

    What with the spark plug colour thing & before the fault code registering, I was thinking coil pack on light coloured spark plug cylinder on way out. Not sure at all now.

    Can you do any checks on injectors ie resistance etc?

    I replaced the injector O ring seals about 2-3 years ago when there was a petrol smell in that area. That isn't there just now though.

    Kinda stumped with which way to go with this without the obvious throw money [that I don't have] at it.

    Any advice will be welcome. I have info from ross tech re fault code [cant upload screenshot for some reason] seems fuel biased not spark.

    For a mixture adaption code first thing I would do is check vac lines, PCV system etc for air leaks. Then check MVB’s on vcds and have a look at the lambda sensor
