#2. Cylinder is misfiring , I changed the spark plugs and changed the coil from #2 to spot #1 and it still reads #2 misfiring I hope I didn't confuse anybody. What else should I check

 

Well...You never answered back on your other thread about oil in your coolant. So. Unless that was resolved, it's kind of pointless to guess. You must still be driving it I assume. Not a good idea (as we advised in the other thread) if there is still coolant mixed with oil.
Did you clear the code after the plug/coil swap? If you didn't, it could be a false code reading.
Fwiw. A compression test would be next on my list.

 

I wonder if oil in coolant and a misfire code could be related? H'mmm: HEAD GASKET? CRACKED HEAD?

If this is a 2006-2007 with an oil cooler, that may be leaking.

But, if you never check back what's the use? Could be "big oil" trying to kill off another customer so they don't have to work anymore.
