It's usually the CAD actuator as already mentioned. If that's not it, the last thing to check is the switch on the transfer case. Sometimes those will fail as well.

If you are getting vacuum I would check the CAD (Center axle disconnect). You may want to go to a posi-Lok cable actuator if you're going to replace the vacuum actuator, better performance and you know it's going to engage!
now is the time to start checking for vacuum leaks. I just fixed a 96 F-150 today with a cracked intake manifold. Look at all of your vacuum lines under the hood, that may include lines to the vacuum booster, the pcv valve, the egr valve, the air box, and in rare cases, even the battery box. If you can't find any leaks there, get a can of ether, start the truck, and spray it at the points where the intake meets the heads. If the RPM revs high or dips really low, you have a leak either in the manifold itself (like a crack) or the gasket has failed and it's time for a new one. I hope this helps.
Recheck all the vacuum lines near the EGR solenoid. The new codes are for the EVAP emissions system. they are codes for incorrect purge flow. You may have left a vacuum line of, switched a couple of lines or forgot to plug something back in.
check to see if your O2 sensors are ok. if they aren't replace em and go from there. it could also be a vacuum line that is messed up or cracked check any line u see and see if they are ok to.
