    What year is the car, can you carry out a paper clip test to see if there are any fault codes stored?
    Could be MAF, could be temp 2 sensor, could be lambda sensor.

    Well I've just replaced the mass air flow sensor on my golf v5 , and it's like a different car.
    No uneven idle anymore , with smooth power delivery , and goes alot better as well.
    If you think about it , the maf sensor is the first point where the ecu and management system electronically controls the running of your car , so if there is the slightest problem there , it will magnify further along the lines , overfuelling and so on.
    So I'd say change it , you have nothing to lose , only make things better hopefully.

    its when you put a paper clip in the dia port and the dash flashes a number of times and gives you the number of the fault

    works a treat on the ol redtop engines
