    Have I a problem with my MAF sensor

    Hi,
    Have a 2003 WRX and engine idles and accelerates smoothly but is down on power above 3000 RPM when the turbo boost should really be coming on song. Its not running rough but is definitely below par and I was wondering if this is likely to be a faulty MAF sensor.
    Thanks

    I have never used a toothbrush. Really.

    Thats quite often, think should be fine every Air filer change or re-oiling (depending on what type of air filter your using).

    OEM paper filter. I think every oil change is OK - it's quick and easy.
