maf high code

I have been doing a little loging since installing my LE2 cam. I keep coming up with a maf high code. Does anyone have a trouble shooting flow chart for this code?
Thanks,
Kory

Re: maf high code

Is it P0103?

The MAF sensor circuit high frequency code sets when the signal frequency exceeds 10,700Hz. That would correspond to about 425gps, at least assuming the stock calibration table. Is your engine capable of flowing that much air? If not, something is causing the MAF to read an unrealistically high air flow. Might be defective.

Lt1 LE heads and LE2 cam with all bolt ons in an 88Iroc.
I would be happy if the engine were flowing that much. I'm seeing about 350 afgs at wot.
