You may have a vacuum leak now from working on the engine.
Did you unhook your battery and do an ECM re-learn after the fix?

I unhooked the battery to clear the engine codes

That bone yard EGR could very well be bad. Bite the bullet and get a new one.

I've never heard of your location and I go to Weston/Sunrise all of the time, hmm

anyway, is the only thing which was replaced was the egr with a junk egr?

Please elaborate on the issue you presently have

next, how does the car behave when stone cold and then how does it behave once it hits closed loop (warm and the sensors are engaged)?

When its cold it has to warm up before i can put it in gear then it idles high and after that when i put it in first gear it idles normal its like the engines trying to go but the car feels like it has no power to move with then when i give it a little more gas it seems to run fine but then at a stop light we do it all again with first and some time while im already moving along if i try to just press on the petal to keep it at a speed i can feel it boog

Your junk EGR might have a vacuum leak, or you may have damaged the vacuum line while working on it.
Try plugging the vacuum port for the EGR at the EGR solenoid or at your TBI unit to see if the problem goes away.

I blocked the egr with my finger no difference same thing with the line going to the egr no difference either and i checked the line it has no pin holes in it so yah i dont know
