2002 Ford Taurus Idles rough and hesitates on slight press of gas pedal?

I have a 2002 Ford Taurus regular 3.0 engine. My car will hesitate upon slight acceleration. Also will not pick up speed or shift properly. My transmission is in good shape so Id like to rule out that.

I have replaced the spark plugs, wires, pcv valve, air filter, oil, ignition coil I used fuel injector cleaner on a 1/2 tank of gas as well. Only thing I have yet to replace is the Crankshaft sensor.
Car shows fault codes
P0316
-Crankshaft sensor defective
-Check connector and wiring to sensor. (have not done yet)
-Check trigger wheel for damage. (have not done yet)

P0303
-Cylinder Misfire on #3
-Ignition system (spark plugs, ignition wires) **replaced these already
-Vacuum Leak (No idea what to do here)
-Injector Fault (bought fuel injector cleaner w/ 1/2 tank of gas)
-High or Low fuel pressure (No idea what to do here)

Power Steering Pressure Switch?

I have a 2001 Ford Taurus 24v 3.0l DOHC. I currently have a power steering leak & found out that the power steering pump & pressure switch needed to be replaced. I bought both parts & managed to install the pump with no problems.

However, I can't figure out where the power steering pressure switch goes. Does anyone know? I've checked the internet along with youtube & can't find anything that can help me. Your answers are appreciated.

Could I trade in my '96 Ford Taurus for a new Taurus model?

I have a 96 Ford Taurus in the green color and it only has 57,000 miles on it. I love the way it drives and everything, but I would like to know if I could trade that in for a newer Taurus model? I'm not talking about the 2015(if I could that would be great), but just a newer, more modern one. Thanks!
P.S. I don't know much about the car industry or dealerships or anything so I'm sorry if I sound really stupid! I don't want to jump into anything and I'm trying to do my research.

2002 Ford Taurus running rough?

My '02 Taurus 3.0L just started running and idling very rough with vibrations under acceleration which were not previously present. The car now has very little acceleration power from a stop or from speed. No check engine light yet but it almost feels like a miss fire. Any clues on what the problem could be?

Air conditioning won't work unless driving?

I have a 2000 Ford Taurus. The air conditioning only works when I'm driving reasonably fast. I thought it was the blower motor, so I changed that but the air still does not work right.

Any suggestions?
