It is possible that this might outstrip your abilities at some point, but probably not.

Check out this website: [http://www.obd-codes.com/p0103](http://www.obd-codes.com/p0103)

It gives the basic troubleshooting. You will need a multimeter of some sort, and when it comes to cleaning the MAF, there is a specific cleaner for MAF sensors (though I suspect it is just relabeled electronics cleaner).

Right - but did you do all of the other basics, like check all of the wiring and the plug itself for problems? Check for proper voltage at the plug? Stuff like that?
