I have replaced all the normal stuff ,MAF, Fuel filter, o2 sensor, cleaned the TB,checked the IAC, EGR, plugs & wires and it still runs like crap.

I would bet the EGR tube has either a hole or a crack in it. You can check it out while still on the car by hooking up your scanner and let the car idle. Take some TB cleaner and spray around that EGR tube real good, the one that goes from the EGR to the lower intake manifold. If it does have a crack or hole you will see the trims come down for a little bit. If so, take it off and inspect it.
