Helppppp!
My truck is throwing codes air/fuel mix too rich, too lean, air flow sensor error and maybe one about the temp of air, its gotten so bad that the truck stalls at any stop and when on the highway letting off the gas gives me a CEL blinking out air/fuel mix too rich, now it doesnt give me the CEL, but i can hear two relays clicking on the passenger side of truck. Also when it is in drive it dies but Shift the auto to N or P and the idle is more reasonable

I'm bringing it to the garage tomorrow moring and would like to have some ideas of what it might be.

You gotta make the title better than that.
You could have any number of bad sensors. Your valves may be seriously out of adjustment, but I would look at you vacuum lines, and make sure your AFM and intake hose are connected and dont have any holes or openings

All indications point to an intake/vacuum leak as the first place I'd look. Use an UNLIT propane/mapp gas torch, running it around ALL the hoses/intake while idling. If it idles up, you have a leak there.
