please???????????

Have you checked the 02 sensors?

Has your computer ever been reprogrammed? If so it may have issues with an aftermarket MAF.

I just bought a 2001 silverado, and the CE light came on 2 blocks befor I got it home. and it was the maf sensor. the dealer replaced it, but it still idles a little rough...... I don't know what to say. replacing the sensor fixed the light.
