Here is a picture of the egr valve for your blazer. http://www2.partstrain.com/store/?Ntt=EGR%20Valve&N=9968%201588%204294967265
Quite pricey. As for changing it out I would head to your local library and seek out their online car repair sources. Be sure to take a jump drive or a floppy disk to take the documents back home with you. From your home print out the proper techniques as well as torque specs for the removal and replacement of the egr valve. Good luck.

Pull vacuum on egr valve with engine idling and see if engine stumbles and tries to die until vacuum is released. If this DOES NOT happen the egr exhaust passage is plugged will need to remove egr valve assembly and remove carbon from passage into cylinder head.

Remove the throttle body housing on the top of the intake, it is a 90 degree tunnel like small piece held by 4 small bolts, turn it over and look for two holes, these holes are for the EGR valve flow, they are probably plugged up with carboned crud, clean them out with the tip of a screwdriver if neccessary to remove all the crud, once its clean reinstall it and reset your check engine light, hope this helps, let me know

SOURCE: EGR VALVE ON 96 FORD PROBE SE
If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
I have to junk my 1996 Probe if I don't find them - Missouri emissions.

OK, if you replaced the EGR hose, did you go all the way to change the EGR Valve? A stuck open EGR Valve can cause a rough idle and almost make it cut off.
Also, a vacuum leak on the EGR valve can cause a rough idle.
Exhaust Gas Recirculation (EGR) Valve Removal & Installation 2.0L Zetec Engine NOTE: When the EGR tube is disconnected from the EGR valve, it must be discarded and a new EGR tube must be installed. The aluminum threads on the EGR valve must be inspected, and a new EGR valve installed if the threads are damaged.
