    MK4 Gti Rev change

    Hey Guys,

    Not sure whether anyone can help me out, but, no better place than this.

    I had a boost/vac hose replaced not long ago and then had all my error codes cleared last night...was driving perfect again, but when i drove it this morning, it's gone back to revving low on idle, give to take just above 600rpm..

    can anyone suggest where to start looking? i can't seem to find a vac leak anywhere. It also goes back to normal if i turn the car off and back on again... So it's kinda intermittent.

    Thanks for your help

    easiest thing to try is disconnect the MAF and see if the idle goes back to normal, could be a bad MAF
