What was the purpose of the maf sensor wiring mod?
#20
This is interesting, because I've never yet seen one which needed the earth fix, but obviously it is quite a common thing. I have had a few come to me with it already changed though.

From the looks of it you only need to do this if you get multiple open circuit faults, if you've just got MAF open circuit it's 99% just a bad MAF. If the TPS and the MAF are open circuit then look in to the earths.
