hate to see you just throwing parts at it but try cleaning the throttle body or could be the TPS.does it miss at idle? or is it smooth till you give it gas? check your fuel pressure and when did you replace your fuel filter?

bad o2s will after it warms up.most of the time it will run good when cold but when it gets to temprature run like crap.check your wiring also near the maf..water pump sensor ect.could be as simple as a bad coil wire.
