What should I clean it with? Sorry for being a bit thick. Will have a look at live data is there a voltage from the maf I should be expecting on idle for example.

Go into data look at both air mass mg/str levels , at idle they should be about equal normally around the 400 mark , bring the revs up and look for them coming up as mirror image of each other , they wont be excatly the same .

Hi, does anyone know where I can buy replacements. It's lost all power on full throttle so I just want to replace them.
