Question 2003 Explorer xlt v8 4.6 P2197

Newbie to this forum asking for some help..
I have a 2003 ford Explorer xlt v8 4.6 with a P2197 code.(02 sensor bank2 sensor1)
I had code P2195 a few months ago and replaced that 02 sensor but just recently truck threw code P2197 and is now starting to idle surge when I stop at a light or just leave it running in park.
Replaced PCV valve and the hose that goes from pcv valve to IAC also replaced Fuel Filter.
Cleaned IAC,Throttle Body and MAF did the old check for vacuum leaks with can of carb cleaner nothing found.
Any Ideas or past experience would be greatly appriciated... Pulled all coil packs off checked OHMs all read .6,coil boots looked to be in good shape going to replace spark plugs and 02 sensor tomorrow so I will post with results.
Thanks

Although most of the replacement items are maintenance, it would be beneficial to connect a LIVE DATA SCANNER and run through the diagnostics, rather than throw random parts... Philip
