The lights came on about a week ago. The book states the problem the problem to be High Air flow output. I need some help interpreting this. does it mean Im running lean?? or does it mean I have clog injectors so not enough gas in the cylinders?? Can someone help. Also I notice a screechy noise coming from my timing belt. I have an 02 WRX and about 68k on it. I thought the timing built is not due for change out til 80K. correct me if I'm wrong.

Does anyone have any suggestion as what to do with my CEL of P0103. The only mod I have is the CAI, and timer and exhaust. but its been in there for a long time now. I do my regular oil change every 5-7k with mobil 1 . Car has 68k on it now. Any suggestion would be great. Thanks

Mass air flow circuit, high INPUT.

Probably your MAF sensing too much air?

I had that CAI a little over 2 yrs now. This is the first time this code came on. These symptoms dont appear immediately? And why so long after I have it on? Im just curious

yeah you have a vacuum leak which is causing the car to run a little leaner it is probobly leaking where the mass air flow goes to the intake tbe get rid of the intake or seal it well with gasket sealer or foam gasket
