**UPDATE**
I thought i'd tackle my EGR(code 71) problem today, and here's what i came up with.....
I started with the VSV.... Removed the VSV, tested it , it was ok. Then i tested the EGR vacuum modulator,it was ok.
And last i removed the EGR valve..........Sure enough there was my EGR problem! OMG was it ever clogged up with gunk and carbon!!!!!! I mean one of the ports(the top one if i recall) was COMPLETLY clogged up with gunk!! So i bought a can of throttle body cleaner and started cleaning it. then i noticed there is a plate (which the egr valve attaches to) that attaches to the intake manifold. the top port on the manifold was also completly clogged with gunk. it was only 2 nuts and two screws to the plate off , so i took it off , cleaned the back side of the plate(was also full of crap!) .Also attached to this plate is the EGR temp sensor if im not mistaken. I also cleaned all the crap off of that. Put everything back together and that was it! No more code 71!!!! i had the battery dissconnected the whole time i was working on it BTW.
The results... SMOOOTH shifts! No more code 71, SMOOOTH idle, and i'll bet way better fuel mileage. Unfortunatly the 0-60 is still the same(10 secs) But top end has improved dramaticlly!!! :D
Here are the procedures..........

"j.barleycorn" had these files posted in some previous threads. thanks .
i was also going to take off the throttle body and clean it, but i looked inside and it looked as if was cleaned recently. Even the back side of the back plate was clean! So that, i dont have to worry about . I still have to tackle the TPS problem. You guys think that has anything to do with my slow 0-60 ??
Well, time and tinkering around further more will only tell. Untill then i'll keep this thread updated . Just glad i'm through with the EGR prob. It was very easy to do BTW. I would recommend that everyone check there EGR valve. It is VERY easy to do and takes 5 mins to take off.
