Tahoe 1996 check engine light

[junkie4mud]

Hey guys need your help. I have a 5.7 vortec motor. 1996 Tahoe

I have a check engine light on my 96" Tahoe. I got it checked at Auto zone here in Nebraska. It said the O2 #1 and #2 are bad and the camshafted sensor are bad. Then the guy said it might just be the mass flow senor might be bad. I don't know what to replace. The Tahoe has a miss driving it. The plugs and wires are kinda new less then a year. Any ideas out here on this forum? Need help soon. Thanks

Unplug the MAF sensor and see if miss is gone.

Does the CAT glow when it runs?

Which sensors? Bank1 Sensor1/Sensor2?

Have you had the intake apart?
