1999 Mazda B2500 won't pass inspection

Generally speaking, the not ready issue means the truck has not been driven enough since the battery was disconnected or the codes were cleared to have a new history. The cycle drive needs to include about 50-100 miles of both city and highway driving with the engine at normal operating temp. The distance does not have to be done in one trip.

Service engine light on no power loss code was for oxsensor changed up and lower light is still on

Maybe the light just needs to be reset "or" after changing some O2-sensor\'s you have to drive the car 50+ miles for the computer to reset and the light to go out. Go to you Mech or Advanced Auto and ask them to connect their meter and reset the check engine light, Advanced does it for free and they will tell you if something else is now wrong; maybe by changing both of those it tripped something else. did you put it on a meter after changing those? And, have you driven the car more than 50mi since changing them? I worked for a car dealer who changed a few O2 sensors in a minivan and I drove the sucker for over 100 miles before that light went out. That original 50+ miles is supposed to be non-stop driving too.

check for a bad connection like a bad ground at the battery, make sure both terminals are tight at the battery, the starter and the ground at the engine. the shop that installed the EGR should have erased the codes, after 50 to 100 miles you would be able to go through emissions.

I would disconnect the battery for at least 20 seconds. Connect the battery drive the car for a least 5 miles at least 50 MPH that should reset it, if not you should have a scan tool connected to see what is going on, take care of the problem and clear the codes
Good luck
