My cylinder #2 is mis-firing and everything I check and replace leads back to the computer. I don't know if I need one or not but if I do what would be the cost of a new one?

Misfire at cyl no. 2 you should check the sparkplug, compression and injector for that cylinder.

Engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel
