I have been getting P0101 MAF code and P0171 and P0173 System too lean on both banks on my 97 Tahoe. I did a Hertz reading on the MAF and the output was completely random at idle and acceleration. I rebuilt the top half of the motor this past summer and upgraded to the new style fuel injectors sand replacing the intake manifold gaskets with the Felpro Permance Gaskets. I am leaning towards replacing the MAF sensor, but it is an expensive part so I am leary of changing it and that's not the problem. Anyone else have a similar situation occur to them?
