Hi everyone. Have been talking to a guy at the gym re the Nissan Skyline Mass Air Flow sensor on our cars after we have found that he is getting about 700km's around town whereas i am getting about 520km's around town. Same vehicle (2008 350GT S), roughly same area times of driving and similar driving styles. i've have noticed that my car is idling quite roughly and he mentioned the Mass Flow Air sensor may be stuffed and this could be causing both the economy difference and the idling problems (as per this listing on TradeMe. http://www.trademe.co.nz/Browse/Listing.aspx?id=937190669)
Wondering if anyone out there can let me know if this could be an issue (have taken the AFM's out and they 'appear' to be ok - my car has just clicked over 50000km's) and worth me replacing them. I can see that there are plenty of other places online overseas selling these a whole lot cheaper than this guy. Cheers for any advise guys.
