Well, your going to have to tell us what the codes were before all the repairs and what codes have returned.

Re: Possible Sierra bad computer
It is possible that the computer iss bad, but you would need to rule out the sensors for those codes and the related wiring first.
Cam and crank codes could be because the distrubutor is off a little bit.
MAF could be a bad sensor or wiring.
Also check for a broken ground on top of the block, passenger side rear, behind the intake manifold right next to the head.
