    when the revs come down from being higher than 1k the revs where dropping down below 1k then goin back up to around 850.
    i took the battery off 2day and put it back on after 30 mins
    then tried the ignition on 4 30 secs thing
    now the revs drop and go back up three times before they settle.
    the drive is still smooth but the revs do this everytime.
    i have fitted the n75j valve and 710n diverter ages ago though

    It could be a dirty MAF as it sounds as if the revs are hunting then settling.
